Manufacturing has been changing from a mainly inhouse effort to a distributed style in order to meet new challenges owing to globalization of markets and worldwide competition. Distributed simulation provides an attractive solution to construct cross enterprise simulations to evaluate the viability of the proposed distributed manufacturing enterprises. However, due to its complexity and high co...

This paper provides an overview of the information model that is under development for the simulation of a manufacturing supply chain. The supply chain simulation is being developed to validate interface specifications as part of the Intelligent Manufacturing Systems (IMS) Modeling and Simulation Environments for Design, Planning and Operation of Globally Distributed Enterprises (MISSION) proje...

conclusions using the simulation as a decision making tool helps us to decide how we can reduce outpatient's waiting time. comparison of outputs of this scenario and the based- case scenario in simulation model shows that combining physician's work time changing with patient's admission time changing (scenario 9) would reduce patient waiting time about 73.09%. due to dynamic and complex nature ...

Today most modern manufacturing systems contain complex units, which are often difficult to model correctly. Therefore, it is desirable for simulation packages used in manufacturing to be flexible, and provide comprehensible modules. This research work presents a methodology of modelling and simulation of a manufacturing system using Arena software simulation tool, in order to deal efficiently ...

This paper describes the scope and configuration of the simulation model that is under development for a manufacturing supply chain. An information model that serves as a neutral interface specification is also presented in the paper. The supply chain simulation model described here is being developed to validate interface specifications as part of the Intelligent Manufacturing Systems (IMS) Mo...

Cycle Time – Throughput curves (CT-TH), which plot the average cycle time versus start rate for a given product mix, are often used to support decisions made in manufacturing settings, such as the impact of proposed changes in start rate on mean cycle time. Discrete event simulation is often used to generate estimations of cycle time at a significant number of traffic intensities (start rates)....

In order to shorten production time, it is wise to use simulation tools at every step of product development. Simulation tools can help avoid iterative steps based on trials and minimize development time—as well as costs. Along with existing WZL software packages (Refs. 1–2), a software simulation tool for gear hobbing has been in development for several years—i.e., PARTApro. Gear hobbing is on...

We describe the application of simulation modeling to estimate and improve quality and productivity performance of a steel cord manufacturing system. We describe the typical steel cord manufacturing plant, emphasize its distinguishing characteristics, identify various production settings and discuss applicability of simulation as a management decision support tool. Besides presenting the genera...

Virtual Manufacturing is a concept of executing manufacturing processes in computer environment as well as in the real word. This paper deals with the NC programming verification processes. It describes the main levels of simulation tasks. The second part of this paper focuses on the object oriented modelling and simulation architecture for simulation of NC machining operation. In this area som...

A case study on the suitability of an existing system configuration and control policy to the manufacturing strategic objectives has been conducted in a discrete part factory that belongs to a large Swedish manufacturing company. There are two market segments for the products identified as Segment A and Segment B with different priority of competitive factors. A newly formulated manufacturing s...
