With the need to extend the life of ageing assets, manage shorter maintenance campaigns and ensure availability of resources, companies are becoming more curious and creative about possible solutions and more willing to collaborate across traditional silos. Oil and gas companies are building more digitally integrated supply chains and are seeing significant results. When a damaged gasket can cost US$1M/day and create a major safety hazard, even early stage implementation of digital technologies can generate significant improvements. A liquefied natural gas (LNG) plant was curious about what they could achieve through better data integration and alignment. Visualising activity plans and digitally integrating equipment strategies through bill of materials improved the plant’s supply responsiveness, increasing both asset availability and production output by 2%. Creatively leveraging automation across the supply chain is helping companies become more connected. Starting with advanced analytics, the building blocks for end-to-end solutions are being built. In the near future, predictive part failures data will automatically load into work management processes, maintenance plans will immediately update and the right parts automatically ordered at the right time. Some companies are experimenting with this ‘virtual handshake’ across departments and systems, creating a smarter, faster and more reliable operation. Using both analytics and improved collaboration, one LNG operation has seen a 40% reduction in duplicate parts, a 30% reduction in inventory and an 8% reduction in overall maintenance cost. Through curiosity, creativity and collaboration across a digitally integrated supply chain, industry organisations can reduce controllable operational cost, making them more reliable and competitive.

Double marginalization effect refers to the phenomenon that when both upstream and downstream firms have monopolistic power, customers pay higher retail price and firms make less profit than when the supply chain is vertically integrated (Tirole, 1988). Although double marginalization effect has been extensively studied in the context of supply chain management for mature products, very limited attention has been given to innovative products whose demand is generated through word-of-mouth effect. The authors study the pricing decisions in a supply chain that sells innovative products. Using a modified Bass diffusion model to capture demand trajectory over time, the authors identify the optimal way for the retailer and supplier to adjust prices when profit is not discounted, and also provide numerical examples when profit is discounted. The authors show that (1) when profit is not discounted the optimal retail prices are adjusted over time, while the optimal wholesale price should be kept as a constant, and (2) double marginalization effect also exists in an innovative product supply chain, but its degree depends on a number of factors, such as the innovation and imitation coefficients.

Motivated by the complex production management with difficulties in error-prone assembly system and inaccurate supply chain inventory, this paper designs a novel manufacturing execution system (MES) architecture for intelligent monitoring based on wireless sensor network (WSN). The technical perspective includes analysis on the proposed manufacturing resource mutual inductance method under active sensing network, appreciation technology of multisource information, and dynamic optimization technology for manufacturing execution processes. From business perspective, this paper elaborates the impact of RFID investment on complex product by establishing a three-stage supply chain model that involves two suppliers carrying out Stackelberg games (manufacturer and retailer). The optimal cost threshold values of technology investment are examined for both the centralized and the decentralized scenarios utilizing quantitative modeling methods. By analyzing and comparing the optimal profit with or without investment on WSN, this paper establishes a supply chain coordination and boosting model. The results of this paper have contributed significantly for one to make decision on whether RFID should be adopted among its members in supply chain. The system performance and model extension are verified via numerical analyses.

This paper presents a new practical game which helps undergraduate students to understand how the concept of supply chain management (SCM) works. The game uses a simple supply chain structure incorporating three entities of the supply chain: supplier, plant, and customer. The game employs a set of toy building blocks such as LEGO® blocks and has the rules of the game, responsibility of each player, product descriptions and bill of materials. This competitive game is used supply chain cost as the measuring to determine the winner team of the game and the Bloom's taxonomy as guidelines to develop the assessment testing based on the learning objectives of courses. This proposed board game has been tested by many undergraduate students who are taking SCM and Logistics Management courses. The results show that the students who played the game reached the higher scores of assessment testing than students who didn't play the game. Furthermore, most students have also positive view about this game.
