Process network solution of a clothing manufacturer’s problem

Abstract

The current work focuses on a Hungarian clothing manufacturer's problem. First the industrial problem is presented; its corresponding critical pass method graph is depicted. To answer all emerging questions with respect to alternative possibilities, a large number of critical pass method problems have to be solved cumbersomely. Instead, first this graph is transformed into a process network. Alternatives specified by mainly financial necessities as well as human resource constraints can now be easily managed, namely where specific activities can be performed in different ways by various employee having different qualifications, requiring different durations and obviously respective costs can be considered within this model. These separate cases can commonly be handled within the resultant sole process network and the corresponding mathematical programming model.

Bus Transport Process Network Synthesis

“…Vincze [25] transformed CPM problems to p-graphs to handle alternatives within one step. Ercsey [26] solved a clothing manufacturer's problem with p-graphs. Benjamin [27] proposed a methodology for criticality analysis of component units or plants in an integrated bioenergy system to increase the robustness against disruptions.…”

Energy Design Synthesis: Algorithmic Generation of Building Shape Configurations

“…The idea to start the algorithmic solution of a specific problem is well-known in the chemical engineering field, for example, [31] presented the p-graph methodology to successfully represent chemical engineering problems to serve as the basis of mathematical programming models. Now, this algorithmic method has been successfully adapted in other fields from handling sustainability issues [32], manufacturing problems by [33], energy storage and distribution by [34], and bus transport optimization [35] to scheduling problems [36].…”
