Analysis of minimum selection H-S/MRC in Rayleigh fading

Abstract: We analyze the error performance of an improved hybrid selection/maximal-ratio combining (H-S/MRC) technique called minimum selection H-S/MRC in flat Rayleigh fading for coherent digital modulation schemes. Here the minimum number of diversity branches are selected such that their combined signal-to-noise ratio is above a given threshold. We derive a closed-form expression for the distribution of the number of selected branches. This distribution is used to obtain the symbol error probability.

Two substitutable perishable product disaster inventory systems

Abstract: A disaster inventory system is considered in which two substitutable items are stored for disaster management. In the event of disaster management, a particular product may become stock-out and the situation warrants that a demand for the particular product during its stock-out period may be substituted with another available similar product in the inventory. From the utility point of view, continuous review inventory models are quite appropriate in disaster inventory management. In this paper, a continuous review two substitutable perishable product disaster inventory model is proposed and analyzed. Since the inventory is maintained for disaster management, an adjustable joint reordering policy for replenishment is adopted. There is no lead time and the replenishment is instantaneous. For this model, some measures of system performance are obtained. The stationary behavior of the model is also considered. Numerical examples are also provided to illustrate the results obtained.

A framework for managing customer knowledge in retail industry

Abstract: Customer knowledge can be a critical source of competitive advantage in retail business. In this theoretical paper, three sources of customer knowledge are identified in the retail environment, namely customer transactions, customer interactions and customer communities of practice. Lessons for managing these three types of knowledge are derived from knowledge management practices of knowledge intensive service industries such as management consulting and software development. Finally, a decision model premised on consumer behaviour and purchase characteristics is proposed. The model would enable retailers to focus their knowledge management efforts to leverage the potential of customer knowledge for both productivity benefits and product innovation.

A goal programming model for optimizing reliability, maintainability and supportability under performance based logistics

Abstract: Reliability, Maintainability and Supportability (R, M and S) are the main drivers of the system operational effectiveness (SOE). New procurement strategies have been developed by both public and private sectors to focus on the R, M and S characteristics inherent to the design of a system. One such strategy known as Performance Based Logistics (PBL) has gained popularity due to its success in improving the operational effectiveness of the system. In a PBL contract the customer buys performance, typically measured using R, M and S metrics, instead of contracting for a specified collection of resources defining the underlying support infrastructure. In this paper we have developed a mathematical model, using Goal Programming to optimize multiple performance measures of a design. We show how the best design is chosen from competing design alternatives when systems engineering principles are considered in defining the evaluation measures. The proposed mathematical model simultaneously considers multiple system engineering metrics during the design stage of the product development. The engineering metrics considered are a representation of the system's operational availability, reliability, maintainability, supportability and total cost of ownership. The Goal Programming model developed in the paper can be easily solved using software such as LINDO, LINGO and Excel Solver.

Mediating Effect of Loyalty Program Membership on the Relationship Between Advertising Effectiveness and Brand Loyalty

Abstract: This study investigates the mediating effect of loyalty program membership on the relationship between advertising effectiveness and attitudinal loyalty as well as behavioral loyalty. Data from customers of a retail chain (members and non-members of the loyalty program), are used to test two models that are based on the quality-value-loyalty chain. Findings reveal that for customers who are not members of the loyalty program, advertising effectiveness does not significantly affect either attitudinal loyalty or behavioral loyalty. However, advertising effectiveness affects attitudinal loyalty of members of the loyalty program. Loyalty program membership mediates the relationship between advertising effectiveness and attitudinal loyalty.
