Manufacturing systems are complex. They consist of many interrelated subsystems and elements. This study proposes and tests a quantitative measure for the manufacturing complexity that results from system design, referred to as internal static manufacturing complexity. The quantitative measure, ISMC, consisting of eight measurable factors identified from the literature. A large set of simulatio...

This paper proposes a model based continuous improvement methodology to support efforts to achieve sustainable manufacturing, i.e., to increase efficiency and reduce environmental impact of manufacturing systems. Past efforts have provided guidance at a high level or with a focus on products. This paper focuses on supporting efforts for manufacturing, in particular, at the factory level. A fram...

In this project, we first planned to model a manufacturing system using a partial differential equation (PDE), since in the theory of traffic simulation and control, PDEs are used successfully for modeling the dynamic behavior of highway traffic. Because these traffic models show good correspondence with manufacturing systems (vehicles = products, highway = manufacturing system), PDEs can also ...

In the manufacture of aero engine components, three key manufacturing processes can be identified. These are welding, heat treatment and mechanical cutting. Depending on what is required in terms of mechanicaland geometrical properties in the final product these processes are typically combined in a certain sequence. It is consistently these three processes, and the modelling and simulation of ...

This paper describes an approach to integrated manufacturing systems. It aims to integrate design and development activities, as well as the entities existing in a manufacturing system. A model of manufacturing systems is presented, including manufacturing entities with different roles and domains related to them. The characteristics of the manufacturing entities are discussed, including change...

this paper presents a summary of the results from the simulation of a given two-stages production system which uses jit. the system consists of an assembly line with two automated assembly cells and two assembly stock points and one manufacturing cell with three manufacturing stock points for storing reserved parts and one receiving stock. carts with fixed capacity are used for handling the par...
