According to Chinese traditional classification, large-sized jackets weight over 10,000 tons and stand in over 100-meter water. Large-sized jackets are different from the normal in construction tonnage, structural dimension and quality control requirements as well as construction difficulty. More complicated construction technology and programme, higher grade of materials, stricter control requirements on node weld and higher risks all need matched stricter, more meticulous and more comprehensive management in planning and scheduling. Combined with construction of LW3-1 deep-water jacket, this paper describes the planning, tracking progress, process control and optimization.

A recent trend in intelligent machines and manufacturing has been toward reconfigurable manufacturing systems, which move away from the idea of a fixed factory line executing an unchanging set of operations, and toward the goal of an adaptable factory structure. The logical next challenge in this area is that of on-line reconfigurability. With this capability, machines can reconfigure while running, enable or disable capabilities in real time, and respond quickly to changes in the system or the environment (including faults). We propose an approach to achieving on-line reconfigurability based on a high level of system modularity supported by integrated, model-based planning and control software. Our software capitalizes on many advanced techniques from the artificial intelligence research community, particularly in model-based domain-independent planning and scheduling, heuristic search, and temporal resource reasoning. We describe the implementation of this design in a prototype highly modular, parallel printing system.

Some of the important factors that are highly considered in NPF are; production processes, waste reeducation and optimization of raw materials. These concerns can be addressed through advance planning and scheduling and thoughtful programming for production, which reflects the goals, taking into account the different alternatives and the limited resources. On this basis the problem was formulated specifically, the problem specifically, taken into account the particular circumstances of NPF Company, special data was collected to configure a model for the planning and control of production processes. Implementation and analysis of all of that depended on brainstorming with the engineers of NPF, and then the marketing studies for finished productswere analyzed. We concluded after all to the study forecasts the future of the company products; based on the results an aggregate plan is designed. Then a production plans for all levels of planning and control of the proposed production quantities of all products are presented.

<p>Mechanical and electrical installation is a very important construction technology in construction engineering. From the perspective of the construction unit, whether the installation technology and procedure are scientific and reasonable will have a direct impact on the final quality of the project, and it is also closely related to the personal and property safety of the residents. Based on this, construction organizers should construct and perfect a standardized installation construction quality management system, clarify management regulations, and control key technical points, so as to comprehensively improve the quality of electromechanical installation projects and improve the project qualification rate. This article will describe the construction technology and quality control strategy of electromechanical installation engineering, aiming to lay a theoretical foundation for the improvement of engineering qualification rate and construction quality.</p>

Good project management in construction means efficient utilization of labor, material and equipment. Development of labor productivity have to be a first-rate and chronic challenge of those who are accountable for cost control of constructed facilities. Material handling, which includes procurement, inventory, shop fabrication and field servicing, requires special attention for cost reduction. The use of latest equipment and progressive strategies has made feasible wholesale adjustments in construction technology in current a long time. Groups which do no longer recognize the effect of diverse innovations and feature now not adapted to changing environments have justifiably been compelled out of the mainstream of construction activities. The frequent problems of construction industry, customers have an essential position to play. With the aid of its procurement methods, the purchaser impacts the manner a construction project is done, because the tactics affect the form of the project delivery system. What sort of procurement procedures are perceived rational, for one, depends at the underlying assumptions about the characteristic of procurement. A recognized guideline in Lean construction (LC) is that production must be conceived along with transformations (T), flow (F), and value generation (V). Alternatively, it is visible necessary to recognize and cope with the risk of value loss with an identical diligence as the other issues had been to date. Materials management plays an important role in project planning and control. Materials represent a major expense in construction, so minimizing procurement or purchase costs.

Advanced planning and scheduling system's (APS) implementation and operation process for elaborating a production schedule in a production environment similar to what is found in industries. The main characteristics and restrictions of a real production environment were thus considered, such as multi-level structure products, production routes with sequential, parallel and alternative operations, more than one resource per operation and alternative resources. In terms of results, this study provides an overview of the main steps involved in the implementation and operational process of an APS system in an industry, providing an important indicator for choosing and using this sort of system. The expectations of APS systems have been high, both from academia and industry in the subject area of manufacturing planning and control. Relative the massive interest there has not been much written about how APS systems are used in practice and what effects an APS approach really results in.
