MODEL PROPOSAL FOR TOTAL PRODUCTIVITY MEASUREMENT AND EVALUATIONIN A SMALL AND MEDIUM MANUFACTURING ORGANISATION

The question of total productivity measurement in SMEs is still not realised in a complex form. The methods of productivity measurement and performance evaluation used lie in partial productivity ratios or main economic indicators only. Because of that, this paper deals with the proposal of a methodology and a model for productivity measurement and performance evaluation in a manufacturing organisation of small and medium size. The main focus of the paper is on the core of a transformation process and analyses the individual production steps in detail. Except the flow of material throughout the system, the work is capable of cost analysis, which evaluates a manufacturing company’s performance within a present period of time or the comparison of individual activities over time. The essential part of this productivity measurement and evaluation tool is a benchmarking module that creates the conditions for the comparison of internal and external productivity and performance ratios with company’s benchmarks.

MATHEMATICAL MODEL FOR LOGISTIC CONTROL IN INDUSTRIAL CLUSTER

Entry of the Czech Republic into the European Union (EU) means an expressive expansion of space for European integrated logistics development and application. Basically logistics changes are necessary if the companies and also state in the Czech Republic do not want to be an outsider on the European market. Logistics is one of the important points of enterprise within a cluster. Cooperation of cluster members on the field of logistics for involved companies means a substantial advantage which companies will gain against their competitors not only on the native but also on the foreign markets. Conclusions of the research of mathematical model for logistic control in an industrial cluster are the critical points of this paper. This mathematical model shows the main logistic advantages for cluster members.

THE IMPORTANCE OF THE INFORMATION SYSTEM´S QUALITY IN THE CONCEPT OF THE KNOWLEDGE ORGANIZATION AND THE RELATION TO THE PROCESS ANALYSIS (THEORETICAL BASIS AND PRACTICAL EXPERIENCE)

This contribution concerns the problems of information system in the broadest meaning of the word and the approaches and methods used to analyse it. This work examines how they are percepted in present days and what is their mutual relationship. It outlines the possibilities and problems of analysis, defines the relationship of information system and processes. Anyway, many analytic instruments and methods´ results give the similar output as our motto. This contribution emphasizes the importance of the holistic comprehension of the term “information system” and the importance of its general quality in relation to principles of modern management.Motto:„We are drowning in the oceans of data, missing the information we need“E.M.Goldratt

IMPLEMENTATION OF THE CQT METHODOLOGY FOR BUSINESS PROCESS OPTIMIZATION

This contribution deals with business process optimization and management. The aim of this paper is to introduce new CQT methodology for process management and optimization. This new methodology combines known principles and methods for the process management and optimization. The CQT (Cost-Quality-Time) methodology target is the quality improvement, process time and cost reduction as principal process management objectives. The contribution presents also a practical application of the CQT methodology for printed circuit board manufacturing.

FUZZINESS AND PROBABILITY FOR PORTFOLIO MANAGEMENT

In the paper the portfolio of financial assets has been formulated using the fuzzy numbers idea and the statistical information concerning assets. The optimization task of the portfolio structure has been formulated for two types of fuzzy numbers. The data from Polish market have been used for exemplary calculations.

AN EFFECTS EVALUATION OF ERP APS SYSTEM IMPLEMENTATION IN THE UNCERTAIN TERMS WITH USING FUZZY MODELING AND INFERENCE

In the paper the approach to forecasting of selected manufacturing company indexes from ERP APS system implementation that makes the element of efficiency evaluation procedure of planned ERP APS system implementation undertaking in a SME is presented. The approach proposed takes into account the present state of enterprise preparation for implementation with existing implementation constraints and uses data from the earlier implementation of the given system with adoption of fuzzy modeling and inference.

THE ASSURANCE OF LIQUIDITY IN A SMALL ENTERPRISE BY THE APPLICATION OF REVERSE APPROACH

This paper presents how to assure the desirable liquidity level in a small enterprise with the application of the reverse approach. It is an alternative approach as compared to the ones that have been applied so far and which were based on the setting conditions required to obtain the desirable financial liquidity level. The example analysed in this paper led to the comparison of the conventional approach results with the reverse approach results.

PRODUCTION PROCESS REAL-TIME OPTIMIZATION BASED ON PROALPHA® APS SOLUTION

The issues regarding systems providing an overall view of the work orders to be manufactured and their demand-oriented and on-schedule finishing are considered. As an example the proALPHA® system that provides an overview for the work orders as well as for the available resource and capacities is presented. The system gives the planner all the options for the control. The presented solution shows the user where corresponding bottlenecks occur and puts the planner in a position to counteract accordingly.

CHOSEN PROBLEMS OF MODELLING ENGINEERING DESIGN PROCESS

An overview of the various models for engineering design process was presented. General Design Theory, Basic Model, Real Design Model were described. Type-2 fuzzy sets implementation on engineering design process was described

SYSTEM OF COOPERATION DESIGN

The problem of system aiding of inter-enterprise cooperation process designing is presented in the article. Development of enterprises’ productivity requires making the start, creation, and extending of cooperative links among enterprises easier. Development of methods and ways of data exchange in cooperation enables creation of aiding computer systems of production cooperation.
