In view of the time interleaving of the relevant processes in runway reconstruction project and the simplification of the relevant processes in current schedule optimization models, runway reconstruction project scheduling is treated the same way as the ordinary construction project, which can’t meet the requirement of the efficient use of limited daily construction time. Statistics of the daily supervision management data in an actual runway reconstruction project are analyzed according to each process respectively. The law of data distribution can help to judge the reliability of the planed schedule and some process with actual physical meaning can be divided into several processes having no physical meanings as the process time interleaving taken into consideration. Then a new equivalent schedule network diagram with independent processes is built to replace the old one and the Critical Path Method (CPM) technique can be used to solve this mathematic problem and develop a schedule. The schedule plan from the modified schedule network diagram can prove the validity of the modified optimization model compared with the one from the ordinary schedule plan method.

The University

Geodetic control network of Quy Nhon University (QNU) is established based on GNSS technology and electronic total station technology in combination with the middle geometrical elevation surveying method, bench mark of network built with firm concrete installed with a centralized insulator cap. The network consists of 11 points, of which 2 points are traversed from the cadastral point of class I, used as the starting points for the traverse. The network is built based on total station method with 2 turns of forward and backward surveying. The network’s leveling height is measured by the middle geometrical elevation surveying method, ensuring compliance with the procedures and rules of the Ministry of Natural Resources and Environment. The research result includes a system of stable and solid network points, together with the coordinates and the leveling height that are closely adjusted by specialized software, control network diagram. Geodetic control network of the QNU is important in setting up map, general plan, planning, construction and serving for teaching and scientific research of the university.

Evacuation Route

An emergency evacuation route is an important component of emergency rescue of for nuclear accidents. A reasonable evacuation route can reduce evacuation times and protect people’s life. The evacuation route of the nuclear power plant is abstracted into a network diagram and a mathematical model of evacuation optimization route based on the graph theory and the parity of spot diagram method in this paper. Road traffic capacity and other external factors that may affect emergency evacuation are considered in the time weight factor for each road. Finally, an example is given to verify the feasibility of the model.

Practical Implications

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings The proposed extension of the dependency network diagram technique enables managers to perform a broader analysis of dependencies among participants in a collaboration, helping them to more accurately comprehend the relationships between the entities in their collaborative environment and, thus, being in a better position of strategically managing resource dependencies. Practical implications The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.
