AbstractThe problem described in this paper deals with construction project scheduling for multi-object projects. The use of the flow shop model allows for quick execution through optimal, simultaneous means of production. The correct order of tasks according to assumed criteria is the subject of a lot of research. In this paper, we have focused on the aspect of multi-project work crews. In practice, we often observe cases where overburdened crews are supported by ones with downtime. This paper presents a newly developed model used to smoothe out schedules in terms of maintaining crew work continuity. A full description of the algorithm and example usage are presented.

Construction Project Scheduling

Prefabricated buildings are the direction of the future development of the construction industry and have received widespread attention. The effective execution of prefabricated construction project scheduling should consider resource constraints and the supply arrangement of prefabricated components. However, the traditional construction resource-constrained project scheduling implementation method cannot simultaneously consider the characteristics of the linkage between component production and on-site assembly construction. It cannot also fully adapt to the scheduling implementation method of the prefabricated construction projects. It is difficult to work out a reasonable project schedule and resource allocation table. In order to determine the relevant schedule parameters that can reflect the actual construction situation of the prefabricated building and meet the scheduling requirements of the prefabricated project, this study proposes a prefabricated construction project scheduling model that considers project resource constraints and prefabricated component supply constraints. Additionally, it improves the design of traditional genetic algorithms (GAs). Research results of the experimental calculation and engineering application show that the proposed project scheduling optimization model and GA are effective and practical, which can help project managers in effectively formulating prefabricated construction project scheduling plans, reasonably allocating resources, reducing completion time, and improving project performance.

The Subject

The subject of the research is the experience of creating and functioning of the Museum of Archeology and Ethnography of the R.G. Kuzeev Institute of Ethnological Research of the UFRC RAS (MAE IEI UFRC RAS), which is an integral part of the academic museum network formed in the second half of the twentieth century. For a long time, the museum has been exhibiting objects that demonstrate the results of archaeological and ethnographic research in the field of studying the history and culture of the peoples of the Southern Urals. The purpose of this article is to provide a brief overview of the creation of the museum, to consider its development to date; to analyze the main directions of work and the results of museum activities, as well as to determine the specifics and prospects for the development of museum activities of the IEI of the UFRC RAS. In the course of the research, the names of scientists and specialists who participated in the formation of collections are named, information about the acquisition of museum funds and state accounting of objects is provided, the features of exposition activity are highlighted, the most interesting exhibitions and current work in this direction are noted, the implementation of excursion activities is shown, the results of project work are highlighted and the most significant projects are described. Attention is also paid to the results of research activities based on archaeological and ethnographic funds, since this work makes a significant contribution to the development of historical science.

The Impact

Construction projects in all regions continues to be developed for the creation of facilities that can be utilized by the community. One of them is the construction of apartments which are now being intensively carried out to meet residential needs for the community. Making a construction project plan always refers to estimates that exist at the time development plan is made, therefore problems can arise if there is a discrepancy between the plans that have been made and the actual reality. So the impact that often occurs is the delay in the time of project implementation which can also be accompanied by an increase in the cost of implementing the project. In the construction project of Cinere Terrace Suites Apartemen & Citywalk, Jakarta there was a delay resulting in a late payment of monthly bill progress by the owner. Based on the above reasons, this research was conducted to find out how the project performance was seen from the cost and time period of the review period. how is the estimated cost and time to complete the overall project work. The method used in the analysis of this study is the Earned Value Method. Based on the results of the analysis carried out for 29 weeks the project performance on schedule has been delayed and cost shows a positive value. For the estimated completion time of the project there is an increase in time whose duration increases from the planned 98 weeks or 685 days to 109,624 weeks or 768 days. While the estimated cost of completing the project from the results of the analysis obtained a value of Rp. 270,147,448,569.16 smaller than the planned cost of Rp. 315,272,727,272.73. With the difference VAC of Rp. 45,125,278,703.57 this shows that there are benefits obtained by the contractor.

This chapter describes the design of a technology-supported learning environment in which small teams of students worked on authentic project tasks to develop a multimedia product for a real client. The students were enrolled in an advanced-level subject offered in a postgraduate education program, with most studying part-time, and many located a distance from the main campus. Jonassen’s (1999) model for a constructivist learning environment was used as the framework for the design of the subject. A key feature of this approach is the use of related cases to support authentic project activities. The specifics of the design were informed by the research and conceptual literature, and by pilot testing with two class groups. The implementation of the subject was the focus of a qualitative case study that investigated learners’ experiences of the environment. A rich set of data was collected, including student assignment work, discussion records and interviews. Analysis of the data provided insights into the role of the cases in supporting the collaborative project work.

Upper Secondary Schools

This study examined the curriculums and implementation of Education for Sustainable Development (ESD) in upper secondary schools in Japan and Sweden and examined and compared the policies and cases of ESD practice. The comparison showed that ESD is present in the national curriculums of both countries, but is emphasized differently. In Sweden, it is more a matter of mentioning ESD as part of the principles that guide education, while in Japan, the integration of ESD into the subject syllabus is emphasized. The schools visited strove to implement ESD in their work. ESD is not an exclusive approach in addition to other school activities, but rather a central part of the schools´ work. Many issues are included under the umbrella of ESD, not only environmental issues. International contacts are one of the most important elements of the work, but this does not exclude local engagement. In fact, the schools have established impressive networks. Project work is an important approach in supporting students’ learning about sustainable development. A prerequisite for the successful work of the schools, which all have a certain reputation in the field of ESD, is the dedication of the teachers and the equally dedicated principals who support the work.
