Production plan change-oriented multi-objective constraint material substitution method

The invention discloses a production plan change-oriented multi-objective constraint material substitution method, which comprises the following steps: 1, establishing a material substitution model; 2, establishing a material substitution algorithmic rule; and 3, performing an analysis and decision process of substitute material selection. According to the production plan change-oriented multi-objective constraint material substitution method disclosed by the invention, by aiming at material requirement coordination among a product bill of materials (BOM), a process BOM and a plan BOM, which is involved by the material substitution problem emerging in complex equipment due to a task change during an assembly production process, a multi-constraint and multi-objective-oriented material substitution model is established, and meanwhile, according to different attribute characteristics (a design characteristic, a process characteristic and a plan characteristic) of materials to be used as constrained parameters of material substitution, a substitute algorithm of the selection of different material substitutes so as to realize material section, matching and substitution among products, and therefore, the supply-demand relationship balance between substitute materials and product requirements under the assembly constraint environment of design, the process, the task change and resource capability and the like is guaranteed, on-hand inventory parts or parts expected to arriving in the future are reasonably distributed to meet the kitting requirements, and the goal that the total cost is minimized is achieved.

Discrete type work shop production process management system

The invention relates to a discrete type work shop production process management system comprising a control host, a server, a database, a task management module, a process management module, a flow management module, station display and management modules, a radio frequency tag, a hand-operated radio-frequency writing-in device and a mobile terminal. The server, the database, the task management module, the process management module, the flow management module, and the station display and management module are connected with the control host. The station display and management modules arranged at all stations consist of display device and station management units; and the station management units include work hour statistic devices, overstock prompting devices, and radio frequency readers. The task management module is used for receiving a task and making a plan; the process management module is used for decomposing a production task and sending the decomposed tasks to the corresponding display devices; and the flow management module is used for adjusting a production plan or a station setting situation. On the basis of characteristics of various product types, small batches, and frequent plan changing of the discrete type workshop, the invention provides the discrete type work shop production process management system, so that the real-time performance, coordination, and product quality of enterprise production scheduling can be guaranteed.

Shield tunnel longitudinal internal force non-pre-buried type monitoring method

The invention discloses a shield tunnel longitudinal internal force non-pre-buried type monitoring method. The shield tunnel longitudinal internal force non-pre-buried type monitoring method comprisesthe steps that aiming at a defective part or an environmental-change part, longitudinal lengths of a segment under different stress states are measured, and change values of the longitudinal lengthsof the segment are calculated; inverse analysis of internal force is carried out based on the longitudinal lengths of the segment and the length change values; and based on the inverse analysis results, whether a fracture surface has the necessity of long-time monitoring or not is judged, and monitoring components and parts are installed in a targeted mode so as to perform long-time monitoring onthe structural stress states of the fracture surface. According to the shield tunnel longitudinal internal force non-pre-buried type monitoring method, in terms of structural long-term health, the fracture surface which is really the most dangerous and needs to be monitored for a long time most is a defective position caused by various causes in construction in most cases, due to the fact that construction factors have randomness, defective positions are difficult to predict, environmental-change factors are further difficult to predict either due to plan changes or various special causes, andthe components and parts are difficult to pre-bury. According to the shield tunnel longitudinal internal force non-pre-buried type monitoring method, the components and parts are pre-buried in the later period, so that parts which are the most dangerous and need to be monitored most are monitored accurately.

VTS information intelligent pushing system based on ship automatic identification system

The invention discloses a VTS information intelligent pushing system based on a ship automatic identification system. The pushing system is composed of an AIS message generating and broadcasting module, a ship sailing plan timed pushing module, a ship sailing plan change pushing module, a sailing security related information pushing module and an intelligent reply information pushing module; when the pushing system is started, the system procedure is to start the threads of the sailing plan timed pushing module, the sailing plan change pushing module, a sailing security related information pushing module and the intelligent reply information pushing module; when the information needing to push is produced, the AIS message generating and broadcasting thread finishes the conversion to the AIS broadcasting message from the original information, and the AIS broadcasting message is sent to an AIS base station, the AIS base station finally sends the message to the target ship through a VHF way. The pushing system disclosed by the invention can guarantee the fast, convenient and accurate confirmation of the ship sailing dynamic information and the sailing security related information between a VTS center and the ship, and the occupancy on a VHF communication channel by this type of information communication is reduced at the same time.

Component shipping method based on BIM technology

The invention discloses a component shipping method based on the BIM technology, which comprises the following steps: creating a BIM model, and allowing a component receiver to provide a preliminary component approach plan and a change plan; simulating loading in BIM model; according to the simulation loading, allowing the manufacturer to make the loading auxiliary parts and the loading budget; performing actual loading, if there is any change in actual loading, adjusting the shipment plan, and uploading the special loading arrangement to the loading special case database; after the completionof loading, issuing and transporting the loading list and loading process image data by the transportation team; checking the loading list and sending the result to the manufacturer; performing loading information inquiry, settlement of shipment. The invention adopts a component loading method based on the BIM technology of the structure, simulates loading ahead of time, can predict the componentlayout problem in advance to modify the loading plan, improve the space utilization rate, the component receiving party feeds back the admission information and provides the plan change in time, modifies the loading plan in time, and the cost settlement is clear and convenient.
