ALGORITHM OF SELECTING COST ESTIMATION METHODS FOR ERP SOFTWARE IMPLEMENTATION

The article discusses the problem of selecting estimation methods for cost and implementation time for ERP systems, in case when system modifications are necessary. The authors reviewed the methods available in the literature and characterised the stages of strategic phase in the implementation process. On the basis of the analysis of data range and quality required by each method and the data obtained at different stages, a selection algorithm for each stage was proposed.

DISTRIBUTION OF INFORMATION AND DOCUMENTATION FOR THE MANUFACTURING PROCESSES OF THE HIGH-VARIETY PRODUCTS – CASE STUDY

In the last years the researches in engineering have moved towards customer-oriented manufacturing. The individual customer's require-ments are very important for the company's activities. It results high-variety production. High-variety production like mass customization is facing the challenge of effective variety management. Applying methods of mass customization to the empirical process can improve product development process efficiency and reduce time and cost. The manufactu-ring process requires documentation of the production. Very often, the documentation process and the time of its formation is limited. The article includes an analysis of the modern manufacturing systems and answering the question: how is it possible to produce without having a docume-ntation in paper form. The presented solution is used during the high-variety products manufactured in the SMEs. The method was validated in the conditions of best practice high-variety production.

COMPUTER-BASED SPEECH ANALYSIS IN STUTTER

The paper presents computer aided approach to speech disorder analysis. The three levels definition of stutter is presented for describing this particular problem. The effective speech analysis algorithm used for segmentation of signal and detecting stutter is discussed and samples are presented.

IDENTIFICATION OF BOTTLENECKS IN THE UNIT MAKE TO ORDER PRODUCTION

Since the production is aimed at fulfilling specific needs of demanding customers and not at filling warehouses, the production volume should reflect the volume of orders. In times of fight for the client every order has to be performed on time. What is more, in times of fight for shortening the delivery cycle, meeting safe deadlines, that is distant in time, is not enough. Companies are forced to meet short deadlines with keeping the product price competitiveness condition. It is hardly possible without a advanced planning support system. Currently, advanced planning systems are coming into use, however their cost exceeds the possibilities of small and medium enterprises and algorithms used often require great customization to industries’ needs and conditions of unit and small-batch production. Such conditions lead to a need for simplified methods. The methods used so far are not capable of finding the global optimum of such big data ranges. For this reason computer tools for applying to the industrial scale are needed. The above method basis on the data so far collected in ERP system.

COMPUTER PROGRAMMING AS A TOOL FOR THE ENGINEERING PROBLEMS ANALYSIS

The paper presents the use of computer programming to solving typical engineering problems. First of all, the basic information about the computer programming ideology and types of computer programming languages were outlined. Secondly, the Matlab environment that combines computing, visualization and programming was described. In the final part of the paper the author presented solution of the beam with a uniformly distributed load problem by use of special computer program prepared in Matlab language.
