The business model of the building construction sector of the construction industry has changed very little over the years. The highly fragmented structure of the industry has led to an overwhelming focus on project management vice production control and has resulted in “artificial” constraints that limit the ways in which the physical product actually gets built. These artificial constraints r...

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...

In designing a production system for the fabrication of a product, a manufacturing engineer usually has some control over the extent of the use of subassemblies. He/she may have the freedom to decide whether or not parts or groups of parts should be assembled together before being added to the main assembly. In this thesis, we study the pros and cons associated with that choice. We present a li...

Hybrid analytic and simulation models are used in solving complex problems in a variety of domains, but are less commonly used in production system design. This paper reviews hybrid approaches and their applications, proposes a new hybrid modeling class, and illustrates a cost function for selecting analytic or simulation modeling approaches via a problem solving process. To illustrate the new ...

The assessment of the effectiveness of e-commerce websites is of critical importance to online retailers. However, the current techniques for evaluating effectiveness are limited in that they do not allow for formal empirical measurement of the productivity and performance of the website. In this paper, we use the theoretical perspective of production economics to measure the performance of Int...

One of the key issues in mining is the hauling system. Truck and shovels are the most widely used transportation equipment in mines. In this paper, a two-phase simulation-based optimization is presented to maximize utilization of hauling system in the largest Iranian open-pit copper mine. In the first phase, The OptQuest for Arena software package was used to solve the optimization problem to p...

This paper has analyzed the functioning conditions for technological system of secondary condensation (TSSC) in a typical ammonia synthesis unit AM-1360 series with use system-control approach. The coordinates control vectors and external disturbances have been determined. An algorithm developed predicting vector subsystem decision support under such complex inertial object high metal consumpti...
