This article aimed to review the ability of the Palestinian construction companies to apply the basic tools of statistical process control (SPC) in their concrete production systems for process improvement. A special focus is made on improving the production process of B30 concrete since it is the most widely used type in the Palestinian market. A...

Providing products with higher quality and lower prices is considered to be a competitive advantage for the industrial firms over competitors. This main challenge can be achieved by minimizing the overall production costs and operational time. Lean manufacturing provides many tools and techniques to iden-tify and eliminate wastes and to reduce cost...

This research is an attempt to understand and model the performance of short columns under different ground levels and storey number. This behaviour includes varying axial forced, shear forces, and bending moments under gravity loads. All the results have been taken for the columns at the ground level when the phenomenon of the short column has app...

The purpose of this work is to study quality related problems in polyethylene pipe products and to improve their quality. Design of Experiment methodology will be used in order to find the optimum settings of the production processes parameters and to reduce the defects. Based on data collected and after the analysis the significant factors are hau...

Reduction in operational time and cost is one of the most important factors for the success of factories globally. Especially if the current political and economic environments in a certain country is not usually positive. Palestine is one of the developing counties facing such harsh conditions. Factories there need to strive to run on minimum poss...

The current political and economic environment in Palestine forces factories to strive to run on minimum possible cost to be able to survive. In this work we present an application of Single Minute Exchange of Dies (SMED) in a Palestinian Aluminum profile company. The company has an extrusion line that works in batches, and often needs changing of...

This paper presents a novel methodology for the implementation of the Total Productive Maintenance (TPM) program in the healthcare industry. The study was carried out at a major hospital using in-depth interviews coupled with observations and documents collection. A TPM implementation methodology has been developed for increasing medical devices u...

This paper presents the work implemented and experience gained in designing, constructing and operating a pseudo continuous automatic drilling machine in which the drilling head acts as a two degrees freedom manipulator. The manipulator carries out a complex planer movement to drill parts being transported by a continuously moving conveyor belt. Th...
