There is a trend in fashion product industry that firms launch new styles of their products more frequently. To investigate the optimal style launching strategy for a fashion firm, we propose a two-period pricing model for a fashion product firm. The firm sells a style of products in the first...

With the rapid development of express delivery industry, the service quality becomes a topic of interest for academic research. This paper extended the previous research by studying the learning effect in express delivery industry. We propose a two-period model to analyse how the learning effect...

This research focuses on an open-loop reverse supply chain, which includes a single centralized returns center (CRC) and multiple local collection points (LCPs). Each LCP receives a stream of returned products from consumers and once its inventory reaches its economic inventory level, these...

As the supplement of buyers' original reviews on products, online additional reviews were supported by some B2C websites recently. That is to say, consumers could post their recommendations or comments again in several months. This paper attempts to measure the impacts of additional reviews on...

Cooperative advertising, which usually occurs in a vertical supply chain, is typically a cost sharing and promotion mechanism for the manufacturer to affect retail performance. Research in the literature, however, rarely considers the important phenomenon that advertising has a positive effect...

Vendor managed inventory (VMI) is a supply-chain initiative in which the vendor is authorized to manage inventories of agreed upon stock-keeping-units at retail locations. In this paper, a modified joint inventory policy is introduced for VMI systems where the vendor takes a standard (s, S)...

Aggregate advertising models are functions reflecting the relationship between product sales and advertising expenditure for a market as a whole. In this paper, we proposed a new advertising response model based on consumer population dynamics. Considering that the population dynamics is one of...

Pareto-Koopmans efficiency in Data Envelopment Analysis (DEA) is extended to stochastic inputs and outputs via probabilistic input-output vector comparisons in a given empirical production (possibility) set. In contrast to other approaches which have used Chance Constrained Programming...

This paper presents stochasticmodels in data envelopment analysis (DEA) for the possibilityof variations in inputs and outputs. Efficiency measure of adecision making unit (DMU) is defined via joint probabilisticcomparisons of inputs and outputs with other DMUs and can becharacterized by solving...
