Todays, efficient management of logistics activities is an important source of creating competitive goals advantages. Besides, Due to increasing the environmental concern, government legislation and natural resource constraint, closed loop supply chain has attracted much attention. Hence, the interest for reusing products and materials has been increased. So considering environmental goals in supply...
Prediction of municipal waste generation is a challenge for decision making and planning, because proper planning and operation of a solid waste management system is influenced by municipal solid waste (MSW) streams analysis and forecasting of solid waste quantities generated Time series modeling is widely used in prediction studies. This study focuses to analyze, compare and select the best time...
Strategic management can be defined as the art and science of formulating, implementing, and evaluating cross-functional decisions that enable an organization to achieve its objectives. The strategic management process consists of three stages: Strategy formulation, strategy implementation, and strategy evaluation. Strategy evaluation or measure and evaluate strategies performance is the final stage...
This The maximal covering location problem (M.C.L.P) was originally developed to determine a set of facility locations which would maximize the total customers' demand serviced by the facilities within a predetermined critical service criterion. However, on some problems that differences between the demand nodes are covered or the number of nodes each node is large, the method of solving MCLP may...
Strategic management focuses on integrating management, marketing, production/operations, finance/accounting, research and development, and information systems to achieve organizational success. Strategic management allows Organization to make effective long-term decisions, to execute those decisions efficiently, and to take corrective actions as needed to ensure success. Evaluating strategies on...
The paper highlights post-production customer connectivity processes in an automobile manufacturing set-up. Identity of post-production processes has been established as a unique in- company service operations or pseudo-manufacturing activities. Consequently this research observes that handling these activities purely with a manufacturing focus or with a pure service focus would not be that effective...
In this paper a bi-objective multi-product EPQ model is developed where defective products produce with a random rate while shortage are allowed and backordered. The objective functions are aimed to minimize total inventory costs and total required warehouse space to store products, where inventory costs include ordering costs, holding costs, backordering costs and purchasing costs. Different technical...
Real options analysis (ROA) is an approach for evaluating investment and strategic projects. And it helps manager in making decisions in an uncertain and highly competitive business environment. In contrast with common discounted cash flow (DCF) approaches, ROA is capable of taking strategic flexibilities and managerial innovations into account. ROA is in fact using the concept of financial options...
In this study, we generalize the Weibull distribution to a new class referred to as the generalized weighted Weibull (GWW) distribution with one scale parameter and two shape parameters. It is investigated that the new model has increasing, decreasing and upside-down bathtub shaped hazard. Several statistical and reliability properties of this new class of distribution are obtained. Estimation, Simulation...
In this paper, an inventory model for deteriorating items with time and price sensitive demand is developed. Deterioration rate is assumed to follow Weibull distribution with known parameter. In the real world, Conditions of uncertainty costs have a direct impact on corporate profits. Therefore in this paper costs is considered as fuzzy numbers. The purpose of this paper is to find the optimal selling...
Supply chain network design is one of the most important problems that managers deal with in supply chain management (SCM). This paper presents a mathematical model for closed-loop supply chain network design. By solving the mathematical model facility locations, the flow of material and number of vehicles are determined such that the total supply chain costs are minimized. Due to complexity of the...
Due to the emergence of new information technologies, there has been an increase on the use of statistical tools applied in business. Here, we investigate several scales existing in literature and propose a novel way of measuring the level of adoption of statistical tools. The logic behind is: The higher a company on the scale; the stronger its statistical capabilities are. Four drivers are investigated...
E-commerce develops rapidly driven by information technology. The order-driven production with many varieties of small batch is prevalent in the supply chain of electricity business. However, high product variety and quick response, especially delivery on time, are always conflicting. Considering the agile supply chain's characteristics of e-business, an assemble-to-order system with a tandem queuing...
