REVIEW OF THE TEXTBOOK WRITTEN BY PROFESSOR RAMŪNAS PALŠAITIS “FUNDAMENTALS OF BUSINESS LOGISTICS”

The textbook “Fundamentals of Business Logistics”, written by professor Ramūnas Palšaitis appears as a very expected and useful publication. The lecturers and students were waiting for this publication for a long time, because till now we did not have such a systematized and particular monograph, which would analyse logistics and could be used for the logistics study process. By now, every known textbook and monograph of other authors was more or less acceptable for studying logistics, but in many cases it has some problematical points, it analyses only one point of the common logistics science, it is not of practical use and cannot be applied for every day activities. In the textbook “Fundamentals of Business Logistics” written by professor Ramunas Palšaitis we can find an orbicular view of the theoretical understanding of logistics and put it into practical use. Consequently, this publication could be useful for both students (during their study process) and businessmen in the business companies, who are active in the sphere of logistics.

Simulation modelling for logistics re-engineering in the construction company

Much attention is being paid to the significant role of logistics in the construction industry, with reference both to the total supply chain and to its individual links, called the ‘internal logistic system’. Rationalization of activity in the logistics sphere leads to lowered production costs and increased quality. However, rationalization of logistic processes often involves re-engineering, i.e. reconstruction or making changes, for instance in the structure of supply chains, in the organization of physical and information flows, in ways of taking up decisions, etc. This paper describes the effectiveness of a simulation modelling approach in improving logistic systems in construction, by applying information collected from Polish construction practice. Graphical and analytical models of company logistic systems are the basis for making simulators using GPSS World™. Two models of different structures from the point of view of physical and information flow were chosen, several different strategies for controlling these flows were worked out, values of particular parameters of the model were defined and the optimum solution was sought. The assumed optimization criterion is minimizing logistics costs. An analysis of the research results can be used to indicate re-engineering needs for the internal models of the logistic systems investigated.
