Aiming at the production stability of complex parts, a method based on weighted network was proposed to analyze the stability of the process routes of complex parts in order to improve the production stability. The weighted network of the process routes of complex parts was constructed by using the concept of machining cell which can transform the production cost and manufacturing time to the weights of network to do the decision-making of the process routes. Based on the production stability, the brittleness risk entropy of subsystem of weighted network was constructed by analyzing the probability of the brittle events that may lead to the collapse of the weighted network in machining cells. As the indicator of analyzing the vulnerability of weighted network node, the brittleness risk entropy can predict the easily failed subsystem in the entire network. Meanwhile, the brittle event, which may lead to the machining cell failure, was retrospect for the greater stability of the process routes. Finally, the correctness and effectiveness of this method were verified by using the manufacturing process of an aero-engine blade.

“…Operation selection refers to the activity of determining the relevant manufacturing resources and selecting necessary operations to obtain the machining features of a given part, while operation sequencing is the activity of determining an optimized sequence of all operations subject to different constraints among operations. [1][2][3] In fact, a part may have m features, among which each feature could be manufactured by one or more machining operation, each operation can be executed by several alternative plans if different machines, tools, fixtures are chosen for this operation. Many optimal objectives have been used to sequence those operations, such as minimizing the number of setups, maximizing the machine's utilization, minimizing the number of tool changes.…”

For the high machining precision and various complicated constraints, process planning of cylinder block always receives lots of attention from industry and academic fields. FMEs (feature machining elements, FMEs) is proposed in this paper, which subdivided from design features and had a close correlation with machining methods according to machining accuracies and manufacturing resources. Therefore, the problem of process planning could be represented by an optimal sequencing and balancing of those FMEs. After analysis of constraints of features and FMEs, an optimal objective is established during a certain stage, and a process planning is generated and optimized by using an improved genetic simulated annealing algorithm (GSA). Finally, a case of cylinder block reveals that the proposed method is feasible and efficient.

In order to solve the problems of flexible process route and workshop scheduling scheme changes frequently in the multi-variety small batch production mode, a multiprocess route scheduling optimization model with carbon emissions and cost as the multi-objective was established. At the same time, it is considered to optimize under the existing machine tool conditions in the workshop, then the theory of logistics intensity between equipment is introduced into the model. By designing efficient constraints to ensure reasonable processing logic, and then applying multilayer coding genetic algorithm to solve the case. The optimization results under single-target and multi-target conditions are contrasted and analyzed, so as to guide enterprises to choose a reasonable scheduling plan, improve the carbon efficiency of the production line, and save costs.
