Sammanfattning
One of the recent concerns for the western companies is the use of appropriate IT support for production planning and control in order to improve utilization of their resources. The offered integrated solutions should be able to cover business processes as well as manufacturing processes in the whole supply chain and to respond to changes in the companies’ environment, strategy, and customer requirements. According to The PPA studies of Swedish manufacturing companies, there is a significant gap between operation times in reality and in the planning systems. One reason for this problem is the operation times in the classical structure of MPCS are updated rarely. This thesis work studies a modern level structure of MPCS that comprises three levels: business management level including ERP or APS systems, MES (Manufacturing Execution System) level, and production level. The integration of MES, as middle layer of MPCS, with the other levels provides real-time information and helps managers to make decision based on facts. Although specific functions are assigned to each level, there are no clear boundaries between these levels and the functions included in each level can be moved with respect to each company’s circumstances. The term “MES” is examined from two aspects, first functions covered by the software and then the non-functional requirements that should be considered for implementing and operating MES solutions. Furthermore, the study analyzes the capabilities and functionalities of software solutions introduced to the Swedish market in each level of MPCS as well as their performance with regards to the feedback from customers. The information collected is based on literature reviews, responses to a web- questionnaire and the study of IT vendors’ websites. Generally to select and implement a right MPCS package, some items should be considered. As an example, Industry type and size of the company that is interested to implement the package, number of users, functionality needed in each department of the company, the language requested, budget for the project, capabilities of the vendor all to be considered. Additionally, the functionalities of existing software solutions in the market should be evaluated with respect to the needs of the company. The implementation should be applied in several small control phases by a team which includes representatives of different sectors of the company and also an IT vendor. Since this project is not able to investigate about the influence of 3-level structure of MPCS on the performance of Swedish companies, further studies must be done to confirm the capabilities of MES level.
