All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0012] At present, in coal preparation plants, the traditional methods of preparing and adding reagents have the following main problems: manual preparation is prone to inaccurate ratios of reagents and water due to operational errors, which affects the coal preparation effect; manual preparation requires a lot of time and manpower, reducing production efficiency and resulting in low preparation efficiency; operators need to operate equipment frequently, resulting in high labor intensity; the preparation amount cannot be dynamically adjusted according to the real-time production volume of the production system, resulting in poor real-time performance of the preparation.

[0013] Based on this, the present invention provides an intelligent dispensing system and method, which can alleviate the above-mentioned problems existing in the existing coal preparation agent preparation technology.

[0014] To facilitate understanding of this embodiment, firstly, a smart medicine dispensing system disclosed in an embodiment of the present invention is described in detail. Figure 1 As shown, the intelligent dispensing system may include: a control subsystem 100 and a sensing subsystem 200, a dosing subsystem 300, a water adding subsystem 400 and a mixing subsystem 500 connected to the control subsystem 100, and the mixing subsystem 500 is also connected to the drug storage subsystem 600; the dosing subsystem 300 may include a dosing hopper 301, a dosing device 302 and a dosing blower 303; the mixing subsystem 500 may include a stirring barrel 501 and a rotary valve 502 connected to each other; the sensing subsystem 200 may adopt a plurality of different types of sensors, the water adding subsystem 400 may adopt a water pump or other equipment capable of transporting water, the dosing device 302 may adopt a dosing motor or other equipment capable of transporting powder, and the drug storage subsystem 600 may adopt a container capable of storing powder; the stirring barrel 501 may be equipped with a stirring motor and a stirring paddle, and the stirring paddle is driven to rotate by the stirring motor, and the speed of the stirring motor may be adjusted according to the dispensing requirements.

[0015] See also Figure 1 As shown, the sensing subsystem 200 can be used to monitor in real time the weight information of the medicine powder added to the medicine adding hopper 301 , the water flow information of the water adding subsystem 400 , and the liquid level information of the mixing barrel 501 .

[0016] See also Figure 1 As shown, the control subsystem 100 can be used to: determine whether medication is required based on liquid level information and preset liquid level threshold information; if it is determined that medication is required, then based on weight information, water flow information and preset medication information, control the medication delivery device 302 to transport the medicine powder in the medication hopper 301 and control the medication blower 303 to blow the transported medicine powder into the mixing barrel 501 and control the water adding subsystem 400 to add water to the mixing barrel 501, then control the mixing barrel 501 to stir and mix the blown-in medicine powder and the added water to prepare the medicine, and control the discharge valve 502 to transport the prepared medicine in the mixing barrel 501 to the medicine storage subsystem 600.

[0017] An intelligent dispensing system provided by an embodiment of the present invention can determine whether dispensing is needed based on the real-time monitored liquid level information of the mixing barrel and the preset liquid level threshold information. When it is determined that dispensing is needed, the system controls the delivery of the powder, the blowing of the powder into the mixing barrel, and the addition of water to mix the powder to prepare the medicine based on the real-time monitored powder weight information and water flow information and the preset dispensing information. The prepared medicine is then stored, thereby realizing full automation of the dispensing process, reducing manual operations, improving dispensing efficiency, and improving dispensing accuracy, which is beneficial to improving coal selection effects. Moreover, the dispensing process is controlled based on real-time information, which improves the real-time nature of dispensing and is beneficial to ensuring the timeliness and accuracy of medicine supply.

[0018] As a possible implementation, see Figure 1 As shown, the liquid level information may include the liquid level of the mixing barrel 501, and the preset liquid level threshold information may include a preset first liquid level threshold; based on this, the control subsystem 100 can also be used to: if the liquid level of the mixing barrel 501 is lower than the preset first liquid level threshold, it is determined that medication is required; if the liquid level of the mixing barrel 501 is not lower than the preset first liquid level threshold, it is determined that medication is not required.

[0019] As a possible implementation, see Figure 1 As shown, the control subsystem 100 can also be used to: simultaneously control the dosing device 302 to transport the powder in the dosing hopper 301 based on weight information and preset dosing information and control the dosing blower 303 to blow the transported powder into the mixing barrel 501, and control the water adding subsystem 400 to add water to the mixing barrel 501 based on water flow information and preset dosing information.

[0020] In actual application, the discharge end of the dosing device 302 can be set near the air outlet of the dosing blower 303, and the air outlet of the dosing blower 303 can be connected to the interior of the stirring barrel 501 through a guiding pipe, so that when the dosing device 302 transports the powder in the dosing hopper 301, the dosing blower 303 can blow the powder flowing out of the discharge end of the dosing device 302 along the pipe into the stirring barrel 501, thereby ensuring the stability of the dosing process.

[0021] As a possible implementation, see Figure 1 As shown, the preset dispensing information may include the volume of the mixing barrel 501 and the frequency adjustment parameters of the dosing blower 303, as well as the preset powder production speed, powder consumption per ton of coal, agent concentration and water-to-drug ratio. The weight information may include the first weight of the powder in the dosing hopper 301 at the current moment and the second weight of the powder in the dosing hopper 301 at the target moment before the current moment. The water flow information package may include the flow rate of water added to the mixing barrel 501 by the water adding subsystem 400; based on this, the control subsystem 100 can also be used to: determine the first powder weight and water volume required for each dispensing based on the volume of the mixing barrel 501, the agent concentration and the water-to-drug ratio; determine the frequency of the dosing blower 303 based on the first weight, the second weight and the frequency adjustment parameters and the time interval between the current moment and the target moment.

[0022] For example, Figure 1 For example, the weight of the first powder, the amount of water, and the frequency can be calculated as follows: Assume that the concentration of the drug is C (unit: kg / m³), the volume of the mixing barrel 501 is V (unit: m³), ​​the water-drug ratio is R (i.e., the mass ratio of water to drug), the weight reading of the drug powder in the drug hopper 301 at the current moment is M1 (unit: kg), the weight reading of the drug powder in the drug hopper 301 three seconds before the current moment is M2 (unit: kg), the frequency of the drug blower 303 is F, and the preset frequency adjustment parameter of the drug blower 303 is K; Based on the volume V of the mixing barrel 501, the drug concentration C, and the water-drug ratio R, the amount of drug powder M' (i.e., the weight of the first drug powder, unit: kg) required for each dispensing can be calculated: ; Based on the volume V of the mixing barrel 501, the drug concentration C, and the water-drug ratio R, the amount of water W (unit: kg) required for each drug dispensing can be calculated: ; After the dosing blower 303 is turned on, the falling speed v of the medicine powder in the dosing hopper 301 (i.e., the amount of medicine powder delivered per second by the dosing device 302, unit: kg / s) can be calculated based on the weighing readings M1 and M2: ; According to the falling speed v of the medicine powder in the medicine dosing hopper 301 and the preset frequency adjustment parameter K of the medicine dosing blower 303, the frequency F of the medicine dosing blower 303 can be calculated: .

[0023] See also Figure 1 As shown, the control subsystem 100 can also be used to: each time the medicine is dispensed, if the first weight reaches the first medicine powder weight, the medicine dosing device 302 is controlled to start so as to convey the medicine powder in the medicine dosing hopper 301 through the medicine dosing device 302, and at the same time, the medicine dosing blower 303 is controlled to start so as to blow the conveyed medicine powder into the mixing barrel 501 according to the above-mentioned frequency through the medicine dosing blower 303, until the medicine dosing device 302 completes conveying the medicine powder, then the medicine dosing device 302 is controlled to stop, and the medicine dosing blower 303 is controlled to stop.

[0024] See also Figure 1 As shown, the control subsystem 100 can also be used to: control the water adding subsystem 400 to start each time the medicine is dispensed so as to add water to the mixing barrel 501 through the water adding subsystem 400 until the above flow rate reaches the above water volume, and then control the water adding subsystem 400 to stop.

[0025] As a possible implementation, see Figure 1 As shown, the preset dispensing information may also include the bottom area of ​​the mixing barrel 501; based on this, the control subsystem 100 may also be used to determine the target liquid level that the water added to the mixing barrel 501 needs to reach each time the medicine is dispensed based on the bottom area of ​​the mixing barrel 501 and the above-mentioned water volume.

[0026] Continuing from the previous example, Figure 1 For example, the target liquid level can be calculated as follows: Assume that the bottom area of ​​the mixing barrel 501 is S; Based on S and the calculated amount of water W required for each dispensing, the liquid level L that the water added to the mixing barrel 501 needs to reach during each dispensing can be calculated: ;in is the density of water.

[0027] See also Figure 1 As shown, the control subsystem 100 can also be used to: control the water adding subsystem 400 to start each time the medicine is dispensed so as to add water to the mixing barrel 501 through the water adding subsystem 400 until the liquid level in the mixing barrel 501 reaches the target liquid level, and then control the water adding subsystem 400 to stop.

[0028] As a possible implementation, see Figure 1 As shown, the control subsystem 100 can also be used to: determine the second powder weight required per hour based on the powder production speed and the powder consumption per ton of coal; determine the number of times of dispensing required per hour based on the first powder weight and the second powder weight.

[0029] Continuing from the previous example, Figure 1 For example, the weight of the second medicine powder and the number of times of dispensing can be calculated as follows: Assume that each time of drug preparation is carried out using drug powder blown into a mixing barrel 501 and water added to the mixing barrel 501, the drug powder production speed of the drug powder production system (i.e., the drug powder production volume per hour) is Q (unit: m³ / h), and the drug consumption per ton of coal is p; Based on Q and p, the amount of powder M required for dispensing per hour can be calculated as: ; The single dispensing satisfaction rate (denoted as P) can be calculated as:

[0030] The number of times medication is dispensed in one hour (denoted as N) can be calculated as: When P is greater than or equal to 1, N=1; Otherwise (i.e. P is less than 1), .

[0031] See also Figure 1 As shown, the control subsystem 100 can also be used to control the respective working states of the dosing device 302, the dosing blower 303, the water adding subsystem 400, the stirring barrel 501 (specifically including a stirring motor and a stirring paddle) and the discharge valve 502 based on the above-mentioned dispensing times, so as to achieve the above-mentioned dispensing times.

[0032] As a possible implementation, see Figure 1 and Figure 2 As shown, the sensing subsystem 200 may include a weighing device 201, a water flow meter 202 and a first liquid level sensor (not shown in the figure); the weighing device 201 can be used to monitor the above-mentioned weight information in real time; the water flow meter 202 can be used to monitor the above-mentioned water flow information in real time; and the first liquid level sensor can be used to monitor the above-mentioned liquid level information in real time.

[0033] As a possible implementation, see Figure 1 and Figure 2 As shown, the above-mentioned intelligent dispensing system may further include an alarm subsystem (not shown in the figure) connected to the control subsystem 100; the medicine storage subsystem 600 may include a medicine storage barrel 601; the sensing subsystem 200 may further include a second liquid level sensor (not shown in the figure) for real-time monitoring of the liquid level of the medicine storage barrel 601; based on this, the control subsystem 100 may also be used to: if the liquid level of the medicine storage barrel 601 is lower than the preset second liquid level threshold and / or the liquid level of the mixing barrel 501 is lower than the preset first liquid level threshold, then the alarm subsystem is controlled to alarm.

[0034] As a possible implementation, see Figure 1 As shown, the control subsystem 100 may include a programmable logic controller (PLC) and a human machine interface (HMI), and the PLC is connected to the sensing subsystem 200, the dosing subsystem 300, the water addition subsystem 400, the mixing subsystem 500 and the HMI respectively; based on this, the control subsystem 100 can also be used to: respond to a control trigger operation for the HMI, and control the respective working states of the sensing subsystem 200, the dosing subsystem 300, the water addition subsystem 400 and the mixing subsystem 500 through the PLC.

[0035] See also Figure 1 As shown, the control subsystem 100 can also be used to display at least one of the following through the HMI: weight information, water flow information, liquid level information, preset liquid level threshold information, preset medication information, and the respective working status information of the sensing subsystem 200, the dosing subsystem 300, the water adding subsystem 400 and the mixing subsystem 500.

[0036] For ease of understanding, the structure and working principle of the above-mentioned intelligent medication dispensing system are described as follows using a specific application as an example.

[0037] See also Figure 1 and Figure 2 As shown, the intelligent dispensing system may include: a control subsystem 100, a dosing hopper 301, a weighing device 201, a dosing motor 3021, a dosing blower 303, a water flow meter 202, a water adding subsystem 400, a mixing barrel 501, a rotary valve 502 and a medicine storage barrel 601, the mixing barrel 501 is connected to the rotary valve 502, the rotary valve 502 is connected to the medicine storage barrel 601 through a dosing pipe, and the mixing barrel 501 is equipped with a stirring paddle and a stirring motor that drives the stirring paddle to rotate. And a first liquid level sensor for real-time monitoring of the liquid level in the mixing barrel 501, the medicine storage barrel 601 is equipped with a second liquid level sensor for real-time monitoring of the medicine liquid level in the medicine storage barrel 601, the control subsystem 100 is respectively connected to the weighing device 201, the dosing motor 3021, the dosing blower 303, the water flow meter 202, the water adding subsystem 400, the stirring motor, the transfer valve 502, the first liquid level sensor and the second liquid level sensor, and the control subsystem 100 is also connected to the alarm subsystem.

[0038] See also Figure 2 As shown, when dispensing medicine, the flow direction of the medicine powder is as follows: the medicine adding hopper 301, the weighing device 201, the medicine dispensing motor 3021, the medicine adding blower 303 and the stirring barrel 501.

[0039] See also Figure 2As shown, the dosing hopper 301 is located before the weighing device 201 and is used to transfer externally added powder (specifically, powder added from a powder bucket or other powder storage container) to the weighing device 301 (generally located below the discharge port of the dosing hopper 301) for weight measurement. The dosing hopper 301 is made of stainless steel, offering excellent corrosion resistance and durability. The design of the dosing hopper 301 takes the flowability of the powder into consideration, ensuring smooth powder transfer from the dosing hopper 301 to the weighing device 301.

[0040] See also Figure 2 As shown, weighing device 301 is used to accurately measure the weight of the powder, ensuring accurate dispensing. Weighing device 301 utilizes a high-precision load cell and is connected to control subsystem 100. This provides real-time feedback to control subsystem 100 on the weight of the powder in dosing hopper 301. When the current powder weight measured by weighing device 301 reaches the set value, control subsystem 100 automatically activates dosing motor 3021 to begin subsequent powder delivery.

[0041] See also Figure 2 As shown, the dosing motor 3021 is connected to the control subsystem 100 and is used to transport the powder under the control of the control subsystem 100, ensuring that the powder can be smoothly added from the dosing hopper 301 to the mixing drum 501 through the combined action of the dosing motor 3021 and the blowing of the dosing blower 303. Under the control of the control subsystem 100, the dosing motor 3021 can automatically start and stop according to the dispensing needs.

[0042] See also Figure 2 As shown, the dosing blower 303 is connected to the control subsystem 100 and, under the control of the control subsystem 100, is used to blow the powder delivered by the dosing motor 3021 into the mixing barrel 501, ensuring that the powder is evenly dispersed in the water added to the mixing barrel 501. The air volume and pressure of the dosing blower 303 can be adjusted based on the size of the mixing barrel 501 (such as volume, bottom area, height, etc.) and the properties of the powder. Under the control of the control subsystem 100, the dosing blower 303 can be automatically started and stopped according to the dispensing needs.

[0043] See also Figure 2 As shown, the water flow meter 202 is connected to the control subsystem 100, and is used to measure the amount of water entering the mixing barrel 501 and to provide real-time feedback to the control subsystem 100 on the volume information of the water added to the mixing barrel 501, thereby ensuring that the medicine powder and water added to the mixing barrel 501 can be dispensed according to the calculated target concentration, and accurately adding the target volume of water to the mixing barrel 501 under the control of the control subsystem 100.

[0044] The stirring motor of the mixing barrel 501 is connected to the control subsystem 100 and is used to drive the stirring paddle under the control of the control subsystem 100 to stir and mix the added powdered medicine and water to achieve dispensing, ensuring that the powdered medicine is evenly dissolved in the water. The first liquid level sensor of the mixing barrel 501 is connected to the control subsystem 100 and is used to monitor the liquid level information in the mixing barrel 501 in real time and provide real-time feedback to the control subsystem 100. When the liquid level in the mixing barrel 501 falls below a set first liquid level value, the intelligent dispensing system automatically triggers the control subsystem 100 to control the water addition subsystem 400 to perform a water addition operation (for example, if the water addition subsystem 400 includes a water pump and a water inlet valve provided on the mixing barrel 501, the water addition operation involves starting the water pump and opening the water inlet valve so that the water pump can pump water through the water inlet valve into the mixing barrel 501).

[0045] See also Figure 2 As shown, after the preparation is completed, the flow direction of the prepared medicine is: mixing barrel 501, transfer valve 502 and medicine storage barrel 601.

[0046] See also Figure 2 As shown, the transfer valve 502 is connected to the control subsystem 100 and is used to control the flow direction of the prepared medicine in the mixing tank 501. Under the control of the control subsystem 100, the medicine is smoothly transferred from the mixing tank 501 to the medicine storage tank 601 for subsequent use. The transfer valve 502 is an electric valve that can automatically switch valve states according to control signals sent by the control subsystem 100.

[0047] See also Figure 2 As shown, medicine storage barrel 601 is used to store medication. The capacity of medicine storage barrel 601 should be designed based on production needs to ensure it can meet continuous production requirements. A liquid level sensor equipped with medicine storage barrel 601 is connected to control subsystem 100 to monitor the medication level in medicine storage barrel 601 in real time and provide real-time feedback to control subsystem 100. When the medication level in medicine storage barrel 601 falls below a set second level, the intelligent dispensing system automatically triggers the alarm subsystem of control subsystem 100 to sound an alarm and remind the operator to refill the medication.

[0048] The control subsystem 100 is the core component of the intelligent dispensing system, responsible for remote control and automatic dispensing. It uses a combination of PLC and HMI to automate the entire dispensing process.

[0049] See also Figures 1 to 3 As shown, the control flow of the control subsystem 100 is as follows: Step S1, system startup: The operator performs a corresponding startup trigger operation through the HMI (such as clicking the start button displayed on the HMI). The PLC responds to the operation and starts the system. The system initializes the status of each component and various preset parameters.

[0050] Step S2, Liquid Level Monitoring: The liquid level information of the medicine and water in the medicine storage tank 601 and mixing tank 501 is monitored in real time using the respective liquid level sensors (corresponding to the second liquid level sensor in the medicine storage tank 601 and the first liquid level sensor in the mixing tank 501). The system monitors the liquid levels of the medicine storage tank and mixing tank in real time. When the liquid level in the medicine storage tank 601 falls below the second set liquid level value or the liquid level in the mixing tank 501 falls below the first set liquid level value, the system automatically triggers an alarm and alerts the operator.

[0051] Step S3, determining the need for dispensing: Based on the liquid level information of the medicine storage tank 601 and the mixing tank 501, the system determines whether the liquid level is too low (primarily determining whether the liquid level in the mixing tank 501 is below a set first level. Even if the liquid level in the medicine storage tank 601 is too low, the transfer valve 502 can be opened to transfer the medicine in the mixing tank 501 through the dosing pipe to the medicine storage tank 601 for subsequent use). If the liquid level is too low (i.e., the liquid level in the mixing tank 501 is below the set first level), dispensing is required. If dispensing is required, the system proceeds to the next step; otherwise, the system continues to monitor the liquid level information.

[0052] Step S4, calculation of the amount of medicine powder and the amount of water added: The system calculates the amount of water required for each dispensing according to the volume V of the mixing barrel 501, the concentration C of the medicine, and the dispensing ratio (i.e., the water-to-drug ratio R). and powder amount .

[0053] Step S5, target liquid level calculation: The system calculates the target liquid level to be reached each time the medicine is dispensed based on W and the bottom area S of the mixing barrel 501. .

[0054] Step S6, calculation of the number of times of dispensing: The system can also calculate the amount of powder required for dispensing per hour based on the powder production volume Q of the powder production system per hour and the powder consumption per ton of coal p. , and then calculate the number of times N that medicine is dispensed within an hour based on M and M'.

[0055] Step S7, water adding operation: the system automatically adds water to the mixing barrel 501 until the amount of water added to the mixing barrel 501 makes the liquid level in the mixing barrel 501 reach the target liquid level L.

[0056] Step S8, dosing operation: When the current powder weight M1 measured by the weighing device 201 reaches M', stop adding medicine to the dosing hopper 301 and turn on the blower. After the blower is turned on, the system calculates the drop rate based on the comparison between the current powder weight M1 measured by the weighing device 201 and the powder weight M2 3 seconds ago. Then the system calculates the frequency of the dosing blower 303 according to v and the preset frequency adjustment parameter K of the dosing blower 303 The system controls the dosing motor 3021 to deliver the powder for dosing, and at the same time the system starts the dosing blower 303 to blow the powder into the mixing barrel 501 according to the calculated frequency F through the dosing blower 303 until the amount of powder added to the mixing barrel 501 reaches M'.

[0057] Step S9, stirring operation: the system starts the stirring motor equipped with the stirring barrel 501 to drive the stirring paddle to rotate to achieve stirring, ensuring that the medicine powder and water are fully mixed. The stirring time can be set according to the dispensing requirements.

[0058] Step S10, conveying operation: After the stirring is completed (i.e., the medicine powder and water are fully mixed into the medicine), the system opens the transfer valve 502, and transfers the prepared medicine in the mixing barrel 501 along the dosing pipe into the medicine storage barrel 601 through the transfer valve 502 for storage for subsequent use.

[0059] The system dispenses the medicine N times according to the number of times N of dispensing calculated in step S6 (ie, performs the operation process from step S7 to step S10 N times).

[0060] Step S11, system ends: after the medicine dispensing is completed, the system automatically stops the operation of each component and enters the standby state.

[0061] In summary, the core working principles of the intelligent dispensing system mainly include: using the liquid level of the medicine storage barrel 601 and the liquid level of the mixing barrel 501 to determine whether dispensing is needed; calculating the amount of powder, water addition and target liquid level required for a single dispensing; using the dosing motor 3021 to deliver a specific amount of powder, and at the same time using the dosing blower 303 to blow the delivered powder into the mixing barrel 501, and calculating the frequency of the dosing blower 303 based on the falling speed of the powder when the dosing blower 303 blows; calculating the number of times N that medicine needs to be dispensed in one hour (that is, N barrels of medicine need to be dispensed in one hour), and then each time N barrels of medicine are dispensed, the system automatically stops the operation of each component and enters standby mode.

[0062] The beneficial effects of the intelligent dispensing system are mainly reflected in the following aspects: 1) High degree of automation: Through remote control and automatic control, the dispensing process is fully automated, reducing manual operations and improving dispensing efficiency.

[0063] 2) High dosage precision: The use of high-precision weighing sensors, liquid level sensors and water flow meters ensures the ratio accuracy of powder and water, improves dosage accuracy and improves coal preparation effect.

[0064] 3) Good real-time performance: It can dynamically adjust the dosage according to the real-time powder production volume of the powder production system to ensure the timeliness and accuracy of the drug supply.

[0065] 4) Easy operation: Through the HMI interface, operators can easily monitor and control the dispensing process, reducing the difficulty of operation.

[0066] 5) High safety: The system has liquid level monitoring and alarm functions, which can detect abnormal situations in time and ensure production safety.

[0067] The embodiment of the present invention also provides an intelligent medicine dispensing method, which can be applied to the above intelligent medicine dispensing system. Figure 1 and Figure 4 As shown, the intelligent prescription method may include the following steps: In step S401 , the sensing subsystem 200 monitors in real time the weight information of the medicine powder added to the medicine adding hopper 301 , the water flow information of the water adding subsystem 400 , and the liquid level information of the mixing barrel 501 .

[0068] In step S402 , the control subsystem 100 determines whether medication needs to be dispensed based on the liquid level information and preset liquid level threshold information.

[0069] In step S403, if it is determined that medication is required, the control subsystem 100 controls the medication device 302 to transport the medicine powder in the medication hopper 301 and controls the medication blower 303 to blow the transported medicine powder into the mixing barrel 501 and controls the water adding subsystem 400 to add water to the mixing barrel 501 based on the weight information, the water flow information and the preset medication information.

If it is determined that dispensing is needed, the powder delivery, blowing into the mixing barrel and adding water for mixing are controlled based on the real-time monitored powder weight information and water flow information and the preset dispensing information to prepare the medicine. The prepared medicine is then stored, thereby realizing full automation of the dispensing process, reducing manual operations, improving dispensing efficiency, and improving dispensing accuracy, which is beneficial to improving coal preparation effects. Moreover, the dispensing process is controlled based on real-time information, which improves the real-time nature of dispensing and is beneficial to ensuring the timeliness and accuracy of medicine supply.
