The turnover speed of the port is the key to the efficiency of railway and shipping joint transportation of large-scale coal energy enterprises. In view of the situation that the high stock of coal port leads to the difficulty of railway unloading, a ship scheduling optimization model considering the priority of ship queuing is constructed. The model takes into account the characteristics of ships entering and leaving the port, tidal characteristics, and the matching characteristics of berths and ships. Genetic algorithm is designed to solve the optimization model with the optimization objective of reducing the storage and increasing the efficiency of the port. The optimal ship scheduling scheme and ship berth matching scheme are given. The example analysis shows that compared with the traditional manual scheduling scheme based on the priority of ship queuing, the model can realize the rapid reduction of port inventory and improve the ship scheduling efficiency while considering the priority of ship queuing, which verifies the effectiveness of the model.

This paper conducts strategic analysis and development plan design of energy digital transformation from a global perspective. First, this paper analyzes the reasons for the digital transformation of the energy industry, and elaborates on the current status of the digital transformation of the energy industry. Second, this paper uses the "SWOT" model to conduct a strategic analysis of the digital transformation of energy. Finally, this paper uses the "IETB" model to design the development plan. The results showed that: (1) Energy digital transforma-

“…There are several models used to summarize problems in the inflow and outflow in building a fairly accurate Supply Chain Management model (Belov, Boland, Savelsbergh, & Stuckey, 2020). (Belov et al, 2020) Supply Chain Management is built from existing activities in the Supply Chain including factories (Manufacturers), suppliers, transporters, warehouses, and etailers. A supply chain is a network of a series of activities (e.g.…”

This study aims to measure the performance of Supply Chain Management (SCM) using the Supply Chain Operation Reference (SCOR) method in order to optimize every activity in the company's SCM. The research was conducted with a qualitative approach through direct observation, interviewing company experts along with filling out special questionnaires and documentation. Performance measurement will focus on five core processes, namely Plan, Source, Make, Deliver, and Return. There are 18 indicators studied with indicators that have the attributes of Reliability, Responsiveness, Agility. The method used in this study is the Analytical Hierarchy Process (AHP) method which is used to obtain weighting results so that the performance assessment is more precise. The final value is obtained by multiplying the performance value with the weight of importance. This research was conducted at a sand mining company in Yogyakarta. The results of this study indicate that the performance of SCM in the sand mining company is in the good category with a final performance rating of 77.05 from a scale of 0 to 100. For indicators that have a low performance rating below 70, suggestions for improvement will be given. One of the proposed improvements is to provide training and certification to employees. The company is expected to be able to make improvements according to the suggestions given based on the research that has been done.
