Modeling of an inventory system with multi variate demand under volume flexibility and learning Pages 147-158 Download PDF

Authors: Surbhi Singhal, S.R. Singh

DOI: 10.5267/j.uscm.2014.12.006

Keywords: Learning, Multi-variate demand, Stochastic backorder, Volume flexibility

Abstract:

In this study, a volume flexible inventory system for deteriorating items with stock & time dependent demand has been developed over a finite planning horizon. Shortages are permitted with partial backorder. Uncertainties are inherent in real inventory problems due to complexities of market situation. This uncertainty can be handled by the concept of randomness. As a result, backorder rate is taken as random and follows a probability distribution. All the costs are influenced by the learning effect. The optimal number of production cycles that minimize the total cost is considered. Numerical illustrations together with sensitivity analysis are given to elucidate the model. Furthermore, the numerical results of the finite planning horizon model have been plotted graphically.

Abstract:

Supply chain management (SCM) has recently received considerable attention in business management literature. Many companies consider a well-designed SCM and implement it to their systems to increase the performance of production systems. Supplier selection is a fundamental aspect of SCM, which heavily contributes to the overall supply chain performance. SCM is a complicated decision-making problem including both quantitative and qualitative factors. In this paper, we try to determine criteria, indicated by experts for selection of suitable suppliers. The proposed study obtains weight of each criterion by Fuzzy Linear Goal Programming (FLGP) technique. We rank the suppliers by Fuzzy Quality Function Deployment (FQFD) method.

A memo on stock model with partial backlogging under delay in payments Pages 11-20 Download PDF

Authors: A.K. Bhunia, A.A. Shaikh, Sarla Pareek, Vinti Dhaka

Keywords: Delay in payments, Inventory, Mark-up rate, Partial backlogging, Stock-dependent demand

Abstract:

In this paper, we presents an inventory problem where initially, a retailer purchases Q(=P+R) units and after fulfilling the backlogged quantities, there is a P unit of the on-hand inventory. It continuously declines to meet the customer’s demand, which depends on the on-hand inventory level up to the time t = t1. After that the inventory level declines by constant demand up to t = t2. Thereafter, shortage occurs and it accumulates at the rate ?(T-t) till t = T when the next batch arrives. This whole cycle repeats itself after the cycle length T. The proposed model of this paper is investigated under various conditions and the implementation of the proposed model is presented through some numerical examples.

Authors: Saeed Khodayar Yeganeh, Maryam Yokhaneh Alghyani

Keywords: Conservative management, Management honesty, Quality of financial reporting, Supply chain management

Abstract:

Management teams are always expected to provide transparent financial reports for public. Different characteristics such as honesty, conservatism as well as management capability may play essential role for the success of businesses in supply chain. The proposed study of this paper considers the effects of three factors; namely management capability, management honesty and management conservatism on quality of financial statements. The proposed study collects the information of 92 firms from Tehran Stock Exchange over a nine-year period from 2004 to 2012. Using some statistical tests, the study has concluded that only management honesty could influence on quality of financial reports. In our study, conservatism did not have any impact on the quality of financial reports and it seems that managers have to take more risk in order to reach financial objectives.
