Quality Management to continuous improvements in process of Ready Mix Concrete production

摘要

The key benefits from Ready Mix Concrete (RMC) are good quality, lower Life cycle cost, the speed of work and friendliness of environment more than the site mixed concrete, but when the quality of RMC is below threat of several causes resulting poor quality or useless concrete. We will lose all advantages of RMC that we mention before. Therefore, this study investigate the using of Quality management to improve the process of company to produc (RMC) in batching plant and study the impacts of Quality Control (QC), Quality Assurance (QA) on the company by introduce them to the process in order to make improvements on current Quality system to make it continuous improvements. The idea of the work depends on finding the relationship between the Project Management Body of Knowledge (PMBOK) Guide and the quality management by combining them together in process to achieve the best results as soon as possible, higher productivity, less rework, increased customers satisfaction, increased profitability and sustainability by finding company's problems and achieving it through guidelines and instructions of PMBOK Guide also the principles, the tools and the techniques of Quality Management. In order to achieve that, we have investigated three main points: the first one is gathering information to identify the current quality system, the second is identifying and analyzing of these problems and the third is finding solutions based on the principles of management. With a view to manage the process of production, the author used many techniques and tools for management such as Flow Chart for a process, Ishikawa diagrams to define seven main group of problems, Check Sheet to the number of problems occurrence, the FMEA Analysis for thirty-five problems, 5 Whys Analysis to find sources of the problems, Solution effect Analysis to propose the possible solutions. The most important results from this study are the main reasons for the absence of management methodology in the company which is a defect in the Quality system (structure of company, procedure, and resources), lack of management experience and communication and lack interest of Total Quality Management in management methodology. The researcher found lacks in the thoughtful scientific methodology for the management in process of production, therefore the developing of the system of production in the RMC plant is to build a methodology based on a guide of Project Management Body of Knowledge 5th edition because of the maturity level of the project management knowledge areas.
