A manufacturing system design assist device is constituted of an input-output unit 1 serving as a user interface and an arithmetic processing unit 2 that performs the internal processing. The arithmetic processing unit 2 is constituted of a central processing unit (CPU) and a storage device such as a hard disk.The input-output unit 1 includes an input device 11 and an output device 12. A manufacturing requirement setting unit 111 of the input device 11 sets a manufacturing requirement at the time of manufacturing products in a manufacturing system, and an evaluation index setting unit 112 of the input device 11 sets an evaluation index of a manufacturing system design plan.The manufacturing requirement setting unit 111 sets a manufacturing requirement including at least one of a specification of a product manufactured by a manufacturing system, a specification of a production facility that is a constituent part of the manufacturing system, and a production plan for manufacturing a product using the manufacturing system. The evaluation index setting unit 112 sets one or more evaluation indices for evaluating a design plan of the manufacturing system.FIG. 2 is an image diagram of a screen for setting an evaluation index of the manufacturing system design assistance device according to Embodiment 1 of the present invention. For example, the required time, the required number of processes, and the required cost may be selected as an evaluation index at the time of startup. For example, an overall equipment effectiveness index, a net equipment effectiveness index, a quality relation, a delivery satisfaction relation, availability, and worker efficiency may be selected as the evaluation index at the time of operation. A start date and an end date may be selected as a predetermined evaluation period.The evaluation index setting unit 112 sets contents of the evaluation index in a setting screen in which a type of evaluation index value can be selected and a start date and an end date of a period to be evaluated can be designated, as shown in FIG. 2, for example.The arithmetic processing unit 2 includes a manufacturing system design plan generation unit 21 and a manufacturing system design plan evaluation unit 22. The manufacturing system design plan generation unit 21 generates a manufacturing system design plan that satisfies a manufacturing requirement, and the manufacturing system design plan evaluation unit 22 calculates an evaluation result of the manufacturing system design plan on the basis of the evaluation index. An evaluation result display unit 121 of the output device 12 displays an evaluation result of the manufacturing system design plan evaluation unit 22.The manufacturing system design plan generation unit 21 is constituted of a manufacturing system design plan extraction unit 211, an evaluation result storage unit 212, a manufacturing system design rule learning unit 213, and a manufacturing system design rule storage unit 214. The manufacturing system design plan extraction unit 211 extracts a manufacturing system design plan from a manufacturing requirement set by the manufacturing requirement setting unit 111 and an evaluation index set by the evaluation index setting unit 112.The manufacturing system design plan extraction unit 211 extracts a manufacturing system design plan using a manufacturing system design rule of the manufacturing system design rule storage unit 214 having a learning result of the manufacturing system design rule learning unit 213 as a manufacturing system design rule. In other words, the manufacturing system design plan extraction unit 211 extracts the manufacturing system design plan with reference to the manufacturing system design rule.The manufacturing system design plan generation unit 21 generates one or more manufacturing system design plans that satisfy the manufacturing requirement, and extracts one or more manufacturing system design plans in consideration of the evaluation index in the manufacturing system design plan generation unit 211.The evaluation result storage unit 212 receives a plurality of combination results each representing a combination of the manufacturing requirement, the evaluation index, the manufacturing system design plan, and the evaluation result from the manufacturing system design plan evaluation unit 22, and stores them. The manufacturing system design rule learning unit 213 learns a rule for deriving a highly evaluated manufacturing system design plan for a group of the manufacturing requirement and the evaluation index on the basis of the combination result stored in the evaluation result storage unit 212. The manufacturing system design rule storage unit 214 stores a learning result of the manufacturing system design rule learning unit 213 as a manufacturing system design rule.The manufacturing system design plan evaluation unit 22 includes a manufacturing system evaluation calculation unit 221, a manufacturing system startup evaluation unit 222, a manufacturing system execution evaluation unit 223, a production scheduler 224, a production simulator 225, and a control system interface 226. The manufacturing system execution evaluation unit 223 herein evaluates manufacturing execution using at least one of the production scheduler 224 that performs a running plan of a manufacturing facility that manufactures a product and a staff operation plan of an operator, the production simulator 225 that simulates the manufacturing facility and production by the operator, and the control system interface 226 that acquires production actual result data of the manufacturing facility.The evaluation index setting unit 112 sets a startup evaluation index for evaluating a startup operation and a manufacturing system execution evaluation index for evaluating the manufacturing execution at the time of operation, and transmits these evaluation indices to the manufacturing system evaluation calculation unit 221. The manufacturing system design plan extraction unit 211 extracts the manufacturing system design plan with reference to the manufacturing system design rule, and transmits the manufacturing system design plan to the manufacturing system evaluation calculation unit 221.The manufacturing system startup evaluation unit 222 evaluates startup of the manufacturing system on the basis of the startup evaluation index. The manufacturing system execution evaluation unit 223 evaluates manufacturing execution using at least one component s from the production scheduler 224 that performs a running plan of a manufacturing facility that manufactures a product and a staff operation plan of an operator, the production simulator 225 that simulates the manufacturing facility and production by the operator, and the control system interface 226 that acquires production actual result data of the manufacturing facility. In addition, the evaluation result display unit 121 classifies and displays the manufacturing system design plan according to the evaluation index in a predetermined period of time.The manufacturing system evalulation calculation unit 221 classifies the manufacturing system design plan according to the evaluation index in a predetermined period of time on the evaluation result of the manufacturing system startup evaluation unit 222 and the manufacturing system execution evaluation unit 223, and transmits the result of the classification to the evaluation result display unit 121.FIG. 3 is a flowchart illustrating logic of the manufacturing system design assistance device according to Embodiment 1 of the present invention. The manufacturing system design assist apparatus is achieved as an application program on a computer having logic, and outputs a design plan of a preferred manufacturing system for a predetermined condition.The manufacturing system design assist device starts step S 1, inputs the manufacturing requirement to the manufacturing requirement setting unit 111 in step S 2, and inputs the evaluation index to the evaluation index setting unit 112 in step S 3.In step S 4, the presence of the design rule capable of deriving the manufacturing system design plan from the group of manufacturing requirement and evaluation index is confirmed. When there is a design rule in step S 4, the process proceeds to step S 5. If there is no design rule, the process proceeds to step S 6. In step S5, the design plan applying the design rule is generated. More specifically, the manufacturing system design plan is generated from the group of the manufacturing requirement and the evaluation index on the basis of the design rule. After step S 5, the process proceeds to step S 7.In step S 6, an initial design plan satisfying the manufacturing requirement is generated. In other words, an initial design plan that satisfies the manufacturing requirement is generated as a manufacturing system design plan. After step S 6, the process proceeds to step S 7.After the manufacturing system design plan is generated in step S 5 or step S 6, the evaluation of the design plan is calculated in step S 7. More specifically, the evaluation is calculated based on the evaluation index input to the manufacturing system design plan in step S 3.A calculation result of the evaluation as an evaluation result is displayed in step S 8, and then the evaluation result is recorded in step S 9.The design rule is learned based on the evaluation result regarding the derivation of the manufacturing system design plan from the combination of the manufacturing requirement and the evaluation index in step S 10. In step S 11, the design rule recorded in the manufacturing system design rule storage unit 214 is updated.If the manufacturing system design plan is not accepted in step S 12, the process returns to step S 2, and the manufacturing requirement and the evaluation index are changed as necessary, so that the manufacturing system design plan is generated again. When the manufacturing system design plan is assumed in step S 12 with reference to the evaluation result in step S 8, the logic is finished in step S 13.A specification of the product manufactured in the manufacturing system includes at least one parameter of the material, the size, the function, the performance, the component formation, and a manufacturing process of the product to be manufactured, and includes, for example, the material of the product, size data expressing the three-dimensional shape of the product, the accuracy tolerance of the size data, a list of components constituting the product, and the manufacturing process of the product.A specification of the production facility, which is a constituent part of the manufacturing system, has at least one parameter of the size, function, performance, and component formation of the facility used for manufacturing the product, and has, for example, size data expressing the three-dimensional shape of the production facility, the processing type with which the production facility can bypass, and the processing accuracy of the production facility.Three-dimensional CAD data stored as digital data can be used as a way of expressing the three-dimensional shape corresponding to the product or the production facility. The production plan is a plan of the type and the number of manufactured products in a certain manufacturing period, such as monthly, week-based, or day-based, using the manufacturing system.The evaluation index includes the evaluation index at the time of startup and operation of the manufacturing system in a case where the design plan is applied to the manufacturing system. For example, the time, the number of processes, and the cost necessary for startup of the manufacturing system may be selected as the evaluation index at the time of startup.An index value of at least one of a performance index (key performance indicator (KPI)) defined by ISO22400, such as an overall equipment effectiveness index of a factory, a net equipment effectiveness index, a quality relation of a product, and an evaluation index, such as a delivery-fulfilment relation of a product similar to the KPI, may be selected as an evaluation index at the time of operation, for example. The start date and the end date of the period are matched with the production plan so that a predetermined period is set as a period to be evaluated.The manufacturing system design plan is a design plan including at least one concept of a configuration of the production facility, the layout of the production facility, and the operator's personnel. The manufacturing system design plan is evaluated in the manufacturing system design plan evaluation unit 22 on the basis of the evaluation index. An evaluation value for each evaluation index for the manufacturing system design plan is calculated in the manufacturing system evaluation calculation unit 221.The evaluation result acquired by the manufacturing system startup evaluation unit 222 and the manufacturing system execution evaluation unit 223 is used for calculation of the evaluation value. The evaluation value calculated in the manufacturing system evalulation calculation unit 221 is displayed on the evaluation result display unit 121 of the output device 12.For example, when two types of products of a product a and a product b are manufactured in the manufacturing system as the products, a manufacturing method formed of one or more manufacturing processes is defined for the product a and the product b. The manufacturing process is performed using at least one of the production facilities having a producible function and performance.The manufacturing system design plan is defined by the layout of the production facility and the operator's personnel necessary for achieving the production plan of the product a and the product b. The evaluation value of the defined manufacturing system design plan is calculated by the manufacturing system evalulation calculation unit 221. The evaluation acquired by the manufacturing system startup evaluation unit 222 and the manufacturing system execution evaluation unit 223 is used for calculation of the evaluation value by the manufacturing system evaluation calculation unit 221.The manufacturing system startup evaluation unit 222 performs the evaluation of the operation at the time of startup of the manufacturing system. The operation at the time of startup of the manufacturing system includes, for example, an operation necessary for operating the manufacturing system, such as purchase of a new production facility, transfer or removal of an unnecessary production facility, layout change of the production facility, mechanical setting of the production facility, design and development of a control program of the production facility, and operation checking of the production facility.In the evaluation performed in the manufacturing system startup evaluation unit 222, a numerical value for the evaluation index selected by the evaluation index setting unit 112 is calculated from the time, the number of processes, and the cost necessary for startup of the manufacturing system.The manufacturing system execution evaluation unit 223 executes the evaluation of the operation at the time of production execution of the manufacturing system. The operation at the time of production execution of the manufacturing system indicates the execution of the manufacturing based on the production plan performed by the operation by the production facility and the operation by the operator.The operation by the production facility includes, for example, an operation that is executed on the basis of a program stored in a control device of the production facility, such as machining by a machine tool, transfer by a transfer device, and inspection by an inspection device.The operation by the operator includes, for example, an operation directly performed by the operator of a manufacturing site, such as selecting a component, fixing a jig or component to be machined to a machine tool, component assembly by manual work, and condition setting of an inspection device.In the evaluation performed by the manufacturing system execution evaluation unit 223, when the production execution of the manufacturing system is operated by the operation by the production facility and the operation by the operator, a numerical value for the evaluation index selected from the evaluation index by the evaluation index specifying unit 112 such as a total equipment effectiveness index of a factory, a net equipment effectiveness index, a quality relation of a product, and an evaluation index such as a delivery-satisfaction relation of a product is calculated.The production facility and the operator are assigned to calculate the evaluation value based on the production plan, and the result is used for which the production simulator 225, which is a virtual simulation of the manufacturing system design plan, performs simulated production planning calculated by the production scheduler 224. Production scheduler 224, which is commonly marketed as a software product, may be used to determine a production schedule.When the manufacturing system is actually structured based on the manufacturing system design plan and the manufacturing is performed based on the production planner 224, the actual manufacturing system is used instead of the production simulator 225. In this case, production actual result data are acquired by the control device of the production plant via the control system interface 226. Thus, the evaluation value is calculated.The manufacturing system evalulation calculation unit 221 outputs the evaluation value for one or more of the evaluation indices to the evaluation result display unit 121, for each of one or more manufacturing system design plans, on the basis of the evaluation result of the manufacturing system startup evaluation unit 222 and the manufacturing system execution evaluation unit 223.FIG. 4 is an image diagram of a screen displaying the evaluation result of the manufacturing system design assistance device according to Embodiment 1 of the present invention. For example, the time, the number of processes, and the cost at the time of startup, the overall equipment effectiveness index, and the delivery satisfaction relation at the time of operation, and an integrated evaluation are displayed as the evaluation result for each design plan. This FIG. 4 illustrates an example of selecting a selection item at the time of startup and operation according to the item selected in FIG. 2.The evaluation result display unit 121 outputs the evaluation result in table form, with the manufacturing system design plan indicated on the vertical axis and the evaluation index indicated on the lateral axis. As the evaluation index, the evaluation index at the time of startup and the evaluation index at the time of operation set in the evaluation index setting unit 112 are displayed on the lateral axis. The evaluation value for the evaluation index in the lateral axis is displayed as an evaluation result.The average value of the evaluation scores between the manufacturing system design plans is calculated as an integrated evaluation for the manufacturing system design plan on the basis of the evaluation index at the time of startup and the evaluation index at the time of operation used for the evaluation index on the lateral axis, and the average value is additionally displayed on the peak of the evaluation index on the lateral axis. The manufacturing system design plan to be evaluated may be sorted in the order of the evaluation value for each evaluation index displayed on the lateral axis. As a result, the manufacturing system design plan that satisfies the manufacturing requirement can be generated, and the evaluation result can be displayed and compared.As described above, the manufacturing system design assistance apparatus includes the manufacturing requirement setting unit that sets the manufacturing requirement at the time of manufacturing the product in the manufacturing system, the manufacturing system design plan generation unit that generates the manufacturing system design plan that satisfies the manufacturing requirement, the evaluation index setting unit that sets the evaluation index of the manufacturing system design plan, the manufacturing system design plan evaluation unit that calculates the evaluation result of the manufacturing system design plan on the basis of the evaluation index, and the evaluation result display unit that displays the evaluation result. As a result, the manufacturing system design plan that satisfies the manufacturing requirement can be generated, and the evaluation result of the design plan can be displayed and compared.The evaluation index setting unit sets the startup evaluation index for evaluating the startup operation and the manufacturing system execution evaluation index for evaluating the manufacturing execution at the time of operation. The manufacturing system design plan evaluation unit calculates the evaluation results of the manufacturing system startup evaluation unit that evaluates the startup of the manufacturing system on the basis of the startup evaluation index, the manufacturing system execution evaluation unit that evaluates the manufacturing execution on the basis of the manufacturing system execution evaluation index, the manufacturing system startup evaluation unit, and the manufacturing system execution evaluation unit.In addition, the manufacturing system design plan generation unit includes the manufacturing system design plan extraction unit that extracts the manufacturing system design plan from the manufacturing requirement and the evaluation index, the evaluation result storage unit that stores the plurality of results of the combination of the manufacturing requirement, the evaluation index, the manufacturing system design plan, and the evaluation result, the manufacturing system design rule learning unit that derives the rule for deriving the highly evaluated manufacturing system design plan for the group of the manufacturing requirement and the evaluation index on the basis of the combination result, and the manufacturing system design rule storage unit that stores the learning result of the manufacturing system design rule learning unit as the manufacturing system design rule.The manufacturing system design plan extraction unit extracts the manufacturing system design plan with reference to the manufacturing system design rule. In addition, the evaluation result display unit classifies and displays the manufacturing system design plan according to the evaluation index in the predetermined period.The manufacturing system execution evaluation unit evaluates the manufacturing execution using at least one of the production scheduler that performs the running plan of the manufacturing facility that manufactures the product and the operator's personnel operation plan, the production simulator that simulates the manufacturing facility and production by the operator, and the control system interface that acquires production actual result data of the manufacturing facility.Embodiment 2Embodiment 2 has the same configuration as Embodiment 1. Embodiment 2 is different from Embodiment 1 in that forced learning is used and a neural network for learning is caused in the manufacturing system design rule learning unit 213.For example, forced learning may be used for learning in the manufacturing system design rule learning unit 213. Forced learning is a type of mechanical learning in which an agent in a certain environment observes a current state and avoids a problem that determines an action that should be performed. The agent selects the action so that compensation from the environment is detected. The forced learning tends to detect most compensation by the sequential action.A forced learning algorithm is an algorithm similar to dynamic programming. The forced learning is unsupervised learning that updates estimated compensation that will be detected in the future by learning a group of a state and an action so that a preferred action is detected in a certain state. A method of learning various combinations of state and action by simulation is known.Forced learning is performed in which a combination of a manufacturing requirement set in the manufacturing requirement setting unit 111 and a layout of a manufacturing system at the present time is performed; an operator's staff operation is defined as "a state", a layout change of the manufacturing system and the operator's staff operation is defined as "an action", and an evaluation result calculated on the basis of an evaluation index is defined as a result of "the action" in a given period of time is defined as "a compensation". In a learning process of the forced learning, when the action is performed, the state changes, and when the various combinations of the state and the action are learned and as a result the compensation is detected, the evaluation for the combination is determined.The learning process of the forced learning is executed using the production simulator 225, thus an action for the manufacturing requirement to change the layout of the manufacturing system and the personnel task of the operator to the other layout and the other personnel task is acquired, or they are not changed. A rule acquired from the forced learning in this manner is stored in the manufacturing system design rule storage unit 214.When the layout of the manufacturing system and the personnel input of the operator are applied to an actual factory, the evaluation may be calculated on the basis of the evaluation index from the data acquired via the control system interface 226, reflected in the forced learning, and stored in the manufacturing system design rule storage unit 214.In the manufacturing system design plan extraction unit 211, the manufacturing system design plan for enhancing the evaluation of each evaluation index set in the evaluation index setting unit 112 is extracted from the manufacturing requirement set in the manufacturing requirement setting unit 111 on the basis of the rule stored in the manufacturing system design rule storage unit 214.When the forced learning is repeatedly performed and a case example of a combination of an output of a preferred manufacturing system design plan for the input of the manufacturing requirement and the evaluation index can be collected, a neural network that detects the output from the input can be caused to learn using the collected case example as a teacher signal.FIG. 5 is an image diagram illustrating learning of a design rule in a manufacturing system design assistance device according to Embodiment 2 of the present invention, and a diagram illustrating an image of a neural network caused to learn. The element of the manufacturing requirement and the element of the evaluation index are given as the input of the neural network, and the element of the manufacturing system design plan is given as the output of the neural network.The neural network is caused to learn by giving it the combination of the manufacturing requirement and the evaluation index and the plurality of preferred case examples of the manufacturing system design plan for the combination as a teaching signal.The learning result of the neural network can also be stored in the manufacturing system design rule storage unit 214 as a rule, thus it can be used for extracting the manufacturing system design plan in the manufacturing system design plan extraction unit 211.As described above, the manufacturing system design assistance apparatus includes: a manufacturing requirement setting unit that sets a manufacturing requirement at the time of manufacturing the product in the manufacturing system; the manufacturing system design plan generating unit that generates the manufacturing system design plan that satisfies the manufacturing requirement; an evaluation index setting unit that sets the evaluation index of the manufacturing system design plan; the manufacturing system design plan evaluating unit that calculates the evaluation result of the manufacturing system design plan on the basis of the evaluation index; and the evaluation result display unit that displays the evaluation result. As a result, the manufacturing system design plan that satisfies the manufacturing requirement can be generated, and the evaluation result of the design plan can be displayed and compared.The evaluation index setting unit sets the startup evaluation index for evaluating the startup operation and the manufacturing system execution evaluation index for evaluating the manufacturing execution at the time of operation. The manufacturing system design plan evaluation unit calculates the evaluation results of the manufacturing system startup evaluation unit that evaluates the startup of the manufacturing system on the basis of the startup evaluation index, the manufacturing system execution evaluation unit that evaluates the manufacturing execution on the basis of the manufacturing system execution evaluation index, the manufacturing system startup evaluation unit, and the manufacturing system execution evaluation unit.In addition, the manufacturing system design plan generation unit includes the manufacturing system design plan extraction unit that extracts the manufacturing system design plan from the manufacturing requirement and the evaluation index, the evaluation result storage unit that stores the plurality of results of the combination of the manufacturing requirement, the evaluation index, the manufacturing system design plan, and the evaluation result, the manufacturing system design rule learning unit that derives the rule for deriving the highly evaluated manufacturing system design plan for the group of the manufacturing requirement and the evaluation index on the basis of the combination result, and the manufacturing system design rule storage unit that stores the learning result of the manufacturing system design rule learning unit as the manufacturing system design rule.The manufacturing system design plan extraction unit extracts the manufacturing system design plan with reference to the manufacturing system design rule.
