Background: A key element of the evaluation of warehouse operation is the average order-picking time. In warehouses where the order-picking process is carried out according to the "picker-to-part" rule the order-picking time is usually proportional to the distance covered by the picker while picking items. This distance can by estimated by simulations or using mathematical equations. In...
Background: This paper finds initial basic feasible solution and optimal solution to the transportation problem by using MAM's (Monalisha's Approximation Method). Methods: Using the concept of comparison of the transportation problem by other methods of solution, the paper introduces a very effective method in terms of cost and time for solving these problems. This paper extends transportation problem...
The objective is to define on the basis of the literature as well as to test empirically the main factors that affect the cost saving of many retail chains, resulting from deliberate and conscious policies as well as organized activities in the area of product returns management. Methods: Based on a survey developed for the study, standardized interviews were conducted with representatives of trade...
Introduction: Transportation services may be described in systemic categories. Intermodal freight transport is a practical expression of the system approach to transport. Development of the intermodal transport system has brought about the need for the comprehensive grasp of transportation processes. Intermodal transport operators manage the whole transportation service organization process. Hence,...
Background: The RASFF (Rapid Alert System for Food and Feed) is used to quickly mutual information of member countries of the European Economic Area (EEA) on risks in food. A similar trend line course of alert notifications in the RASFF in time to food from the non-EEA countries and the EEA countries, as well as a very high value of the Pearson's r correlation coefficient (0.96) indicated an interdependence...
This paper derives an inventory model is developed for items that deteriorates at a generalized Weibull distributed rate when demand for the items is dependent on the selling price. Shortages are not allowed and price inflation is taken into consideration over finite planning horizon. A brief analysis of the cost involved is carried out by theoretical analysis.
Background: The growing role of public transport and the pressure of economic criteria requires the new optimization tools for process of public transport planning. These problems are computationally very complex, thus it is preferable to use various approximate methods, leading to a good solution within an acceptable time. Methods: One of such method is the genetic algorithm mimicking the processes...
Background: Due to random changes in demand, inventory management is still - despite the development of alternative goods flow management concepts - an important issue both in terms of costs of maintenance and replenishment as well as the level of service measured by inventory availability levels. There are a number of replenishment systems to be used in such conditions, but they are most often formed...
Background: The paper analyzes a significance of distributive trade in contemporary national economies of select European countries (10) from the point of view of employment, gross value-added creation, supply chain establishment, and international expansion. A cause for the paper is a dissatisfactory level of economic development of certain transitional countries on one side and the high distributive...
