By leveraging the power of MIP solvers, we aimed to minimize the overall digitization time while considering various constraints and process dependencies. The book digitization process involves three key steps: cutting, scanning, and binding. Each step has specific requirements and limitations such as the number of pages that can be processed simultaneously and potential bottlenecks. To address these complexities, we formulate the problem as a one-machine job shop scheduling problem with additional constraints to capture the unique characteristics of book digitization. We conducted a series of experiments to evaluate the performance of our proposed approach. By comparing the optimized schedules with the baseline approach, we demonstrated significant reductions in the overall processing time. In addition, we analyzed the impact of different weighting schemes on the optimization results, highlighting the importance of identifying and prioritizing critical processes. Our findings suggest that MIP-based optimization can be a valuable tool for improving the efficiency of individual work schedules, even in seemingly simple tasks, such as book digitization. By carefully considering specific constraints and objectives, we can save time and leverage resources by carefully considering specific constraints and objectives.展开更多

In the process of the handover work, the problems and defects in the construction design stage and the construction progress stage can be found in time, thus laying a good foundation for the safe operation of the nuclear power plant. This paper first briefly analyzes the significance of the handover work of nuclear power plants and analyzes the common problems, work plans and quality management methods, hoping to provide reference value for the managers of related nuclear power plants.展开更多

Therefore, an optimizing rank system is urgently needed. Analytic Hierarchy Process （AHP） and Technique for Order Preference by Similarity to Ideal Solution （TOPSIS） models were used to rank the planning works of 30 urban wetland park based on four mainly factors, which included landscape ecological planning, landscape planning, ecological planning and economic planning. The study indicated that the AHP- TOPSIS model had good discrimination in the classification and ranking of landscape planning works of urban wetland park and it was also applicable to the planning works of other urban greenbelts.展开更多

In 2005,China's total tax revenue topped 3.0866 trillion Yuan (excluding tariffs and agricultural taxes), up 20%and 514.8 billion Yuan over 2004 and exceeding 3 trillion Yuan for the first time. During the 10th five-year plan period,the total tax revenue remitted into the state coffer amounts to 10.9217 trillion Yuan, with an average annual increase of 19.5%; and the revenue in the fifth year more than doubles that in the first year. The fast and steady growth of the tax revenue in pace with the economic growth has greatly enhanced the country's financial strength and provided solid financial guarantee for the country's efforts to build a well-off society in an all-round way.……展开更多

In the process of improvement, the related infrastructure also gradually presents a diversified trend. However, in the process of development, there will also be some problems, the development of construction enterprises, leading to a gradual increase in market competition, some construction enterprises in order to improve their competitiveness, lower the bidding price in the bidding process, leading to the construction market chaos, construction quality is declining. In particular, some enterprises in order to open up new markets, from the construction of traditional industries to new areas of business, gradually lower the price, ignoring the overall quality. Therefore, in today's economic environment, how to balance the advantages and disadvantages can not only achieve a win-win situation of quality and profit, but also require enterprises to improve their own management system, effectively manage the change claim work in the process of project operation, and improve the management plan. Based on the above arguments, this paper analyzes and studies the planning measures and implementation of the alteration claim work in the project management.展开更多

But this comes with certain challenges regarding safety, reliability, cost, legal framework, regulations, etc. however, of all the concern safety and reliability are of utmost importance for researchers and engineers. The current research is focused on the movement of the autonomous vehicle in the work zone. The work zone is one of the most challenging areas for the autonomous vehicle to drive from. This is because the work zones are very dynamic, and all the construction activities are specific to the site condition and cannot always be predefined. The study provides a concept of how pavement marking can be used for smooth <span style="font-family:Verdana;">movement through the complicated work zone. In this study, various pav</span><span style="font-family:Verdana;">ement marking signs have been designed as a concept considering the standard colors and striping width being used in the Manual of Uniform Traffic control device (MUTCD). The study assumes that the movement of the autonomous vehicle will not be exclusive and that it will move with the driver driven vehicle. It is expected that autonomous vehicles will require special pavement marking and signage for smooth movement through the work zone. These pavement marking and signage will eventually become part of standard Traffic Control Plans (TCP) and Maintenance of Traffic Plans (MOT). The research aims to study the current research being done in this area and technology being used for detecting various pavement markings and signages.</span>展开更多
