Efficient Method of An Optimum Construction Company Supplier Selection Supported by Software

摘要

An optimum selection of construction company suppliers is one of the most important processes of the top management. The most of construction processes are realised by many suppliers all over the world and during the process of construction planning it is necessary to find an optimum solution which would cover several criteria. Ensuring control over the outsourced processes does not absolve the organisation of the responsibility to meet all the customer, statutory and regulatory requirements. According to ISO 9001:2008 developed for Quality Management System the type and range of control to be applied to the outsourced process can be influenced by many factors such as a potential impact of the outsourced process on the organisation's capability to provide a product that would conform to the customer requirements and a degree to which the control for the process is shared. There are several factors and criteria for the efficient selection of company suppliers. Our paper analyses these: quality management level of suppliers, an offered price of the construction process or product, time of construction process realisation and other specific criteria. Using the multi-criterion optimising method and scientific synthesis a method of the efficient selection of suppliers for construction processes is proposed: it relies on selected criteria and their importance. The next part of our research results is a proposal of our original software which allows for an optimum selection of suppliers over a short course of time. This efficient method and software is implemented and verified on a real example from a real construction practice. Application of this method and software will increase the efficiency of the construction company supplier selection from the viewpoint of the key criteria of optimising: quality, time, cost and others. This efficient method and software can be applied in any construction company which cooperates with one or more suppliers in a building process. The optimum selection of suppliers can help construction companies save time and money which can be used for a useful company development process.
