We address a problem of inventory management of spare parts in the context of a large energy company, producer of oil and gas. Spare parts are critical for assuring operational conditions in offshore platforms. About 200,000 different items are held in several inventory plants. The inventory system implemented at the company corresponds to a min-max system. The control parameters are decided ba...

a bstra ct background: effective time management is considered important for managers for achieving the goals in an organization. head nurses can improve their efficiency and performance with effective use of time. there has always been a lot of disagreement in understanding time management behaviors of head nurses; therefore, the present study was conducted with an aim to compare the understan...

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, con...

Fouad Riane CREGI, FUCAM, Mons, Belgique Supply Chain Sciences, Middleton, USA Health care costs continue to rise at unprecedented rates in the United States. While past research has addressed optimal patient scheduling to improve the utilization of operating theater resources (physicians, specialized equipment, and operating rooms), little research has attempted to optimize material requiremen...

Inventory planning results are less reliable when the statistical problem of supply chain risk factors is not considered. In conjunction with measurement model, a cross-border e-commerce cold inventory method proposed to effectively address aforementioned issues. This paper aims define fundamental elements network, determine chain's imbalance range, and develop model also calculate ordering cos...

Construction material supply chains have evolved over time to base production and materials management decision-making on demand information from the immediate downstream node in the supply chain. This myopic view leads to demand signal amplification as individual upstream nodes attempt to forecast and fulfill orders. Further compounding this demand distortion is the fact that a great amount of...

A key challenge for the waste management sector is to maximise resource efficiency whilst simultaneously reducing its greenhouse gas (GHG) emissions. For stakeholders to better understand the GHG impacts of their waste management activities and identify emissions reduction opportunities, they need to be able to quantify the GHG impacts of material recycling. Whilst previous studies have been un...

This paper focuses on an inventory model considering imperfect manufacturing and re-manufacturing system under single management. In manufacturing system, the items are produced from original raw materials but in re-manufacturing process, returned and defective items produced in previous manufacturing process are the raw materials. Both the production system shift from ‘ in control state ‘ to ‘...

Members of supply chain carry inventory for different purposes. To effectively reduce the cost of inventory, information sharing mechanism is the key. The inventory can be managed in two ways in supply chain systems. The first one is the centralized inventory management system, in which, the information of inventory is highly exchanged among supply chain members. The other is the decentralized ...
