The problem of finding bottlenecks in flow networks often appears in real world applications like production planning, factory layout, flow related physical approaches and even cyber security. This work introduces intuitive visual mechanisms to enable domain experts and users to visually analyze stable regions of a network and identify critical transitions. Those transitions form a varying bott...

This case study industry manufactures more than 45 different sizes of tubes for 9 different buyers and is one of the largest manufacturers of Automotive Butyl Inner Tubes in India. In the present plant layout the industries main plant has 8 major aisles. Machines are classified based on the operations and order of process. The machine aisles are arranged using cellular manufacturing concept of ...

Because a production logistics system is very complex and dynamic, optimizing its layout accurately and efficiently is difficult and even impossible based on the traditional mathematical method. This paper focus on finding the bottleneck issues in production logistics system and optimizing its layout based on Flexsim software. With an actual case of production logistics system, we can find the ...

A simple VLSI particle-induced yield predictor has been developed that allows us to predict the entire yield of VLSI and also to analyze the bottleneck processing steps and faults. Particles with spherical shape are generated in the production equipment for each VLSI processing step and are deposited on the wafer. The yield predictor accepts as inputs (a) layout description of the VLSI under an...

Value stream mapping is a lean manufacturing technique used to analyze and design the flow of materials and information required to bring a product or service to a consumer. At Toyota, where the technique originated, it is known as "material and information flow mapping". [29] It can be applied to nearly any value chain. Value stream mapping is often associated with manufacturing. It is also us...

There has been increased focus on recycling in Sweden during recent years. This focus can be attributed to external environmental factors such as tougher legislation, but also to the potential gains for raw materials suppliers. Recycling centres are important components in the Swedish total recycling system. Recycling centres are manned facilities for waste collection where visitors can bring, ...

Queueing network modeling of manufacturing systems has been addressed by a large number of researchers. The purpose of this paper is to provide a bibliography of material concerned with modeling of production and transfer lines using queueing networks. Both production and transfer lines have a product-flow layout and are used in mass manufacturing. We denote production lines as flow lines with ...

Flexible manufacturing Systems are automated manufacturing systems which have job shop flexibility and flow shop efficiency. One of the major concerns in Flexible Manufacturing System (FMS) is the minimization of the total flow of material through the system. Facility layout design deals with the arrangement of machines, in order to minimise the total flow of parts in the system. The commonly u...
