Functional areas such as sales, marketing, finance, and operations traditio...

In a topological structure affected by geographical constraints on liking, the connectivity is weakened by constructing local stubs with small cycles, a something of randomness to bridge them is crucial for the robust network design. In this paper, we numerically investigate the effects of adding shortcuts on the robustness in geographical scale-free network models under a similar degree distri...

PT. KINI is a company engaged in the distribution of Indosat products. In process, there often shortage stock for Voucher type, and an excess SP type. The purpose this research to plan product needs before distribution, especially products that experience shortages. application Double Exponential Smoothing forecasting method, Distribution Requirement Planning are expected overcome problems lack...

We propose a mathematical model which considers the series-type product structure with n−1 predecessors. Our objective is to obtain the optimal production functions, in the planning horizon [0,T ], based on the assumptions (1) that the cost of production unit is a linear function of production quantity in a time unit, (2) that sales of finished goods occur at the end of planning horizon, and (3...

Product variety is an important component of consumer welfare, yet many markets have historically been dominated by a small number of best-selling products. The Pareto Principle, also known as the 80/20 rule, describes this common pattern of sales concentration. However, by greatly lowering search costs, information technology in general and Internet markets in particular have the potential to ...

ith the growing proliferation of enterprise resource planning (ERP) systems, including among midsize companies, it becomes critical to address why and under what circumstances one can realize the benefits of an ERP system. In contrast to previous research, this study examines how managers (president, CFO, production VP, etc.) assess ERP success in specific modules (e.g., suppliers and purchase ...

Determining production rate considering costs and revenues in order to maximize profit is one of the applied problems in small and medium size factories. Mostly existing models in production planning consider production system statically and specify production rate, although the factors determining production rate include many different changes in practice. In fact, by increasing the production...

The Internet is known to have had a powerful impact on on-line retailer strategies in markets characterised by long-tail distribution of sales [1]. Such retailers can exploit the long tail of the market, since they are effectively without physical limit on the number of choices on offer. Here we examine two extensions of this phenomenon. First, we introduce turnover into the long-tail distribut...
