The problem starts with the poor working capital position, leading to high raw material cost and uncompetitive final product pricing. This leads to the generation of a very low investible surplus. Not having investible surplus has forced the state-owned manufacturing companies to a financial situation where they are facing severe dearth of capital. The age-old plant and machineries coupled with...

Recommendation for e-commerce with a mix of durable and nondurable goods has characteristics that distinguish it from the well-studied media recommendation problem. The demand for items is a combined effect of form utility and time utility, i.e., a product must both be intrinsically appealing to a consumer and the time must be right for purchase. In particular for durable goods, time utility is...

A company needs to implement several make-to-stock policies apart from a regular make-to-order production, so that the capacity of expensive resources can be fully utilized. The constraints to be considered in such capacity planning problem include finite budget for investing resources, lump demands of customers, decline of products price with time, different product mix for simultaneous manufa...

Abstract. The recent increasing interplay between actuarial and financial mathematics has led to a surge of risk theoretic modeling. Especially actuarial ruin models under fairly general conditions on the underlying risk process have become a focus of attention. Motivated by applications to the modeling of operational risk losses in financial risk management, we investigate the stability of cla...

This paper deals with the reduction in manufacturing cycle time of a product using line balancing algorithm. The case study was undertaken in an industry that manufactures air-oil separators for compressors. Current state value stream map was drawn to identify the problem areas. The scope of study was limited to the bottle neck stations. The bottle neck stations are dedicated to the production ...

F several of the largest supermarket product categories, such as carbonated soft drinks, canned soups, ready-to-eat cereals, and cookies, consumers regularly purchase assortments of products. Within the category, consumers often purchase multiple products and multiple units of each alternative selected on a given trip. This multiple discreteness violates the single-unit purchase assumption of m...

This paper introduces the fleet size and mix pollution-routing problem which extends the pollution-routing problem by considering a heterogeneous vehicle fleet. The main objective is to minimize the sum of vehicle fixed costs and routing cost, where the latter can be defined with respect to the cost of fuel and CO2 emissions, and driver cost. Solving this problem poses several methodological ch...

Deregulation ha~ opened up many opportunities and challenges in the transportation industry opportunities to increase profits and challenges to keep from being outflanked by competition. A goal of particular interest to the scheduled airlines is to set prices more adaptively and to ~hange them more rapidly. A difficult problem arises when many passengers with different itineraries compete for a...

The product rate variation problem minimizes the variation in the rate at which different models of a common base product are produced on the assembly lines with the assumption of negligible switch-over cost and unit processing time for each copy of each model. The assumption of significant setup and arbitrary processing times forces the problem to be a two phase problem. The first phase determ...

Stefan problem with kinetics is reduced to a system of nonlinear Volterra integral equations of second kind and Newton's method is applied to linearize it. Product integration solution of the linear form is found and sufficient conditions for convergence of the numerical method are given. An example is provided to illustrated the applicability of the method.
