This paper presents a method for modeling the dynamic behavior of harbor supply chains and evaluating strategic and operational policies of the proposed harbor supply chain by applying multiagent systems and simulation. The multi-agent systems modeling represent business entities as agents and the involved information and material flows with proposed coordination method for collaborating among ...

A configurable process model is an integrated representation of multiple variants of a business process. It is designed to be individualized to meet a particular set of requirements. As such, configurable process models promote systematic reuse of proven or common practices. Existing notations for configurable process modeling focus on capturing tasks and control-flow dependencies, neglecting e...

This paper presents a method for modeling the dynamic behavior of harbor supply chains by applying multi-agent systems, and evaluating strategic and operational policies of the harbor supply chain by applying simulation. In views of the order fulfillment, this paper considers the order fulfillment process which starts with receiving orders form the customers and ends with having the finished go...

I some supply chains, materials are ordered periodically according to local information. This paper investigates how to improve the performance of such a supply chain. Specifically, we consider a serial inventory system in which each stage implements a local reorder interval policy; i.e., each stage orders up to a local basestock level according to a fixed-interval schedule. A fixed cost is inc...

A finite element model of large strain deformation in machining is presented in the context of using machining as a controlled method for severe plastic deformation (SPD). Various characteristics of the large strain deformation field associated with chip formation, including strain, strain distribution, strain rate, and velocity field, are calculated using the model and compared with direct mea...

In Switzerland, infrastructure construction is frequently discussed in regional sustainable development because it causes extensive movements of materials. But construction itself is of decreasing importance in industrial countries, as we expect a down-slow in growth of the built environment. Hence, the focus of research on sustainability is shifting to management of the existing building stock...

This paper deals with an experimental investigation on the friction stir welding of pure copper. 4 mm thick copper plates have been welded in the butt joint configuration using a conical unthreaded tool, with and without preheating. An electrically heated backing plate has been employed to increase the initial temperature of the plates and to investigate the influence of pre-heating on the weld...

IncorporatingMaterial Balance Principle (MBP) in industrial and agricultural performance measurement systems with pollutant factors has been on the rise in recent years. Many conventional methods of performance measurement have proven incompatible with the material flow conditions. This study will address the issue of eco-efficiency measurement adjusted for pollution, taking into account materi...

In the industries with high capital investment, the manufacturer has to spend a big amount of money for purchasing equipment. To overcome this imposed pressure the investor should utilize all the resources very efficiently for higher productivity and need to meet the customer’s ever increasing demands. This paper reviews both value stream mapping (VSM) and overall equipment effectiveness (OEE) ...

Besides the logistic system the working structures in a company become increasingly important. With the introduction of flexible working structures, the role of workers in a simulation has to be redefined. It is essential to model workers in varying levels of detail. These levels have to match the levels of detail in the simulation of material flow. A specification was developed that summarizes...
