    Managers’ perception of extra days of product ordering characterises behavioral causes of the bullwhip effect that is not yet addressed so far in literature. The study therefore investigates and compares behavioral causes of the bullwhip effect within- and between multinational and local supermarkets in a three-echelon retail chain. Retail chain stock replenishment practices embodied in a survey was distributed to managers of supplier firms, wholesale distribution centres and small retail stores in Indonesia. The data was analysed using ANOVA and post-hoc test. Results show a significant mean difference in extra days of ordering for both MSCs and LSCs. The small retail stores’ perceived extra days of ordering are significantly more than what the supplier firms order upstream. Wholesale DC of both chains experiences no such effect. The study helps managers to deepen their understanding of extra days of ordering practice that is likely to be influenced by human behavior leading to the very bullwhip effect. Further, realising its negative impact on the chain performance, they need to carefully orchestrate their extra ordering practices.

    ABSTRACT In the recent past, Healthcare sector has shown an exceptional growth all over the world. At the same time, rising health consciousness among patients and demand for quality services has resulted in a stiff competition among hospitals. Consequently, hospitals are increasingly focusing on improving the operations to meet the requirements of patients. To meet this requirement, hospitals need to improve and redesign their existing processes. In this mission of redesigning the healthcare systems, simulation modelers have an important role to play. Simulation modelers can help hospitals in delivering high quality healthcare by proposing strategic scenarios that work in synchronization with operations management philosophies. In this study, we extend an effort in this direction by showcasing the use of simulation as a modeling and analysis tool at an Indian ophthalmic hospital. In particular, we model the outpatient department with a goal of achieving a streamlined patient flow. We analyze various scenarios to compute the adequate resources, while maximizing their utilization. This study results in significant reduction in service lead time, especially in the circumstances where every extra minute spent add to the vows of patients and their aids.

  3. Supply Chain Systems Architecture and Engineering Design: Green-field Supply Chain Integration

    Abstract Full PDF Cite DOI: 10.31387/oscm0230158
    This paper developed a new theory for supply chain archi-tecture, and engineering design that enables integration of the business and supply chain strategies. The architecture starts with individual supply chain participants and derives insights into the complex and abstract concept of green-field integration design. The paper presented a conceptual system for depicting the interactions between business and supply chain strategy engineering. The system examines the decisions made when engineering the business strategy, with regards to the supply chain design. The system derived with a new understanding of how strategies are integrated, and what are the implications for engineering successful strategies. The study revealed that sup-ply chain design is not considered in great detail before archi-tecting the business strategies. Thus, companies consequentially experience supply chain problems that are likely to be detri-mental to the growth potentials. The paper also derived with the findings that proactive and pre-emptive involvement of supply chain participants in the strategy engineering process, would lead to a more robust strategic design.

    Expenditures for winter maintenance materials total nearly $20 million annually in a mid-western USA state. During an average winter the State Department of Transportation (DOT) uses approximately 666,000 tons of rock salt and has the capacity to store roughly 617,000 tons of material at various locations. Each year, each county in this Mid-western state establishes a contract through DOT with a salt vendor before the winter season and that vendor supplies all garages in the county for the entire season. In order to develop a systematic salt inventory management strategy that achieves the statewide goals for safety, ordering guidelines for each county that specify when to order and how much to order based on an (R, S)-inventory guideline is developed. These guidelines take into account the history of usage and deliveries in a county, as well as the monthly variation in usage. The inventory guidelines developed for the different areas of the state are based on a weather regression model for the major cities/counties in the state relating usage to weather. The guidelines were tested and refined using a computer simulation methodology. The resulting guidelines are compared to the state’s current DOT guidelines for inventory, as well as compared to the county storage capacities to develop recommendations.

    Abstract Full PDF Cite DOI: 10.31387/oscm0230160
    Continuous technological innovations are forcing businesses to bring automation into its core activities. E-procurement is one of such technological advancement, receives much attention these days as it is a key to optimise supply chain performance, through cost reduction and improved process efficiency. The purpose of this paper is to compare substantial impact of e-procurement and traditional procurement process for MRO (maintenance, repair and overhaul) in an aviation industry through a qualitative case study approach where stages before and after implementation of e-procurement have been analysed to assess the impact on supply chain performance. The study shows that the e-procurement has advantages over the traditional procurement through bringing simplification and transparency throughout the process, reducing turnaround time and also long term relationship with the suppliers along with subsequent cost reduction across the value chain.

    Despite of its type, location or principal market base, today the manufacturing enterprises are bound to adopt sustainable practices like lean principles, integration of processes and inter-organizational collaborations to meet their corporate goals. The majority of studies usually discuss either a system or a subcomponent of the production systems and manufacturing strategies in literature w.r.t. lean production; but the rational (what, why, how) behind each production activity seems to be missing. This paper addresses a comprehensive assessment of the literature on lean production in relation to the green concept, for its significance, feasibility and need for organizations to sustain in the global market. Findings of the review reveal that lean principles along with green model can improve the process flow & employee morale and lower the environmental regulatory non-compliance risk. Further, the environmental and human health risks are often not explicitly considered in lean initiatives that can affect customers & stakeholders throughout the product life cycle, and the manufacturing enterprises working with lean strategies have the possibility of costs sub-optimization and waste reduction from a lifecycle viewpoint.
