The work desires: i) to determine the optimum level of batch size in bottleneck facility and ii) to analyze the effect of common components on work-in-process (WIP) level and cycle time in a multistage production system under uncertainties. The uncertainty is created by machine breakdown and quality variation. Few simulation models are developed based on a live case from a company. The models a...

A technocentric approach to the use of simulation software in production system design uses it as an expert tool to assist system designers in a one ofs design. A human centred approach, in contrast, uses simulation sofmare to support teams of users to make key decisions about system design. In addition, it provides support for continued improvement and development activities by the users. In o...

The customer is the core element of business based on current market situation, even for industrial equipment which customers’ requirements are now very various. It means that the inside processes of the manufacturer should adjust to customer’s requirements: the company must be very flexible among other properties. The challenge is that the flexibility comes from the management of the knowledge...

In this paper, a multi-product economic production quantity problem with limited warehouse-space is considered in which the orders are delivered discretely in the form of multiple pallets and the shortages are completely backlogged. We show that the model of the problem is a constrained non-linear integer program and propose a genetic algorithm to solve it. Moreover, design of experiments is em...

This paper describes process models that characterize the design phase in the supply chain of pipe supports used in power plants. The models are used to study how production system design factors such as batching, uncertainty, and multitasking throughout this phase hamper supply chain performance. These factors all cause an increase in lead time. The models build on the STROBOSCOPE discrete-eve...

The geographically distributed production of fresh food poses unique challenges to the production system design because of their stringent industry and logistics requirements. The purpose of this research is to examine the case of a European fresh food manufacturer’s approach to introduce a scalable modular production concept for an international two‐stage gastro...

We discuss both numerically and analytically how the space-bandwidth product and the information density of lenses scale as functions of their diameter and f-number over many orders of magnitude. This information may be useful for the design of optical computing and interconnection systems. For diffractive lenses, cost is defined as the number of resolution elements the lithographic production ...

This paper describes and generalises experiences from two cases of production system development in the Swedish context. We have observed the successful application of ergonomics to be related to the lack of coordination of human factors across groups responsible for different stages of the production system design process. This problem is magnified by the tendency for ‘ergonomics’ to be the re...

A high-mix, make-to-order production system can become inefficient when non-value added operations consume too much time, space or labour. To address these issues, cell re-layout is conducted and a CONWIP system is proposed. The cell re-layout started with data collection on current layout, product mix and routings, then the current layout was modified to develop several alternatives, and final...

In this paper, the authors discuss the concepts of variability, buffers, and batches, as well as the interactions between them. The discussion aims at contributing to the identification of factors that impact production systems design, which includes the definition of buffer locations, buffer profiles, batch sizes, etc. The authors use a simulation model developed using STROBOSCOPE to represent...
