Construction development in Indonesia is being intensively carried out as a characteristic that Indonesia is a developing country. CV. X is a construction company that has a project in the form of ten shophouses with three floors. The project is planned to start in August 2020 and be completed in December 2021 or for 68 weeks. The change of seasons becomes an obstacle in the work of the project that causes delays. Progress expected by CV. X in 2 months of project work is 8%, but the reality on the project progress field is only 6%. Therefore, this study aims to optimize existing work time so that the delay can be overcome. The method used in this study is Program Evaluation and Review Technique (PERT) with rainfall as the probability. The results of the study found that the project work time can be optimized by 3% and delays can be overcome because the project completion time becomes 66 weeks. The project is still ongoing, so there is still a possibility of error, therefore effective project management must still be considered. Usually in similar studies the probability of time or cost, while in this study use rainfall as the probability.

Operation Risk

Construction of the hotel development is carried out without cessation of the hotel operations have a bigger challenge because of many things such as: accesses to the hotel, material loading area, noise, safety of guests and hotel staff, working time, demonstrations, etc should be well managed in order to minimize the impacts to hotel operation. Risk is the chance of occurrence of adverse events, which is caused by the uncertainty. The research aims to identify, analyze and how the risks can be managed. The method in this research is Descriptive Qualitative Risk Analisis. Respondents determined by Purposive Sampling, from various stakeholders who are competent in this development. The research are identified 47 risks. Eleven risks are unacceptable risk includes  : noise, licensing, planning of MEP works, declining of contractor profit, the rising cost for build a new access roads, land slides, limited parking, hotel access interference,  discomfort of the hotel’s guests and staff, disruption in the project work time and delay of project completion due to interruption by the hotel operations. Nineteen risks are undesirable risk includes: public opinion, decreasing of green open land, insufficient capacity of the existing facilities, difficulties in the hotel's marketing, declining of the hotel room’s selling prices, the declining of satisfaction level of hotel guests, decreasing of hotel’s profits, lack of project scope, nappropriate strategy for supplying material and equipment and lack of competence of the project consultants and contractors, inappropriate standard of job’s handling, lack of quality control, inappropriate  project organizational, improper work methods, limited area for materials loading, decreasing of  cleanliness levels of the hotel, insufficient noise isolation blocks. Ten risks are acceptable risk and seven risks are negligible risk. Major risks are unacceptable and undesirable risk, which are need to be managed by determining their allocation, ownership and mitigation actions.

There are two opponents in a classic network interdiction problem, network owner/defender and interdictor/attacker. Each side has enough information about the other’s possible courses of action. While the network user wishes to run the network in an optimal way, the attacker with the limited resources tries to prevent the optimal operation of the network by interdicting the arcs/nodes of the network. In this study, we investigate project management in a competitive environment using a network interdiction approach. We assume that the project owner/manager strives to minimize the completion time of a Critical Path Method (CPM) based project while an opponent attempts to maximize the minimum completion time by inflicting some delays on project activities with available interdiction resources. Considering both discrete and continuous delay times, we develop two bi-level mixed-integer programming models for the interdictor. Using duality, we then convert the bi-level models to standard single-level models, which are solvable through standard optimization packages. We extend these models to find efficient solutions in terms of project completion time and interdiction resources from the interdictor’s perspective. In this respect, we develop an algorithm to find an efficient solution set for the interdictor. Next, from project manager’s standpoint, we discuss the earliest and latest scheduling times of activities in case of interdiction. Finally, we apply the developed techniques in a marketing project aiming at introducing a new product. The findings may enhance a better project management in an environment where an opponent can adversely affect the project management process by delaying some activities.

Three Phases

In this article practical aspects of using project management in popular restaurants of different countries are considered. Within the framework of this study, the experience of using the Hard Rock Cafe project management tools is highlighted. It is noted that the management of the project in Hard Rock Cafe includes three phases: planning, setting goals, defining the project and organizing the team; drawing up of a calendar schedule of works; control. Considered the project of opening a new restaurant from Pizza Duono (Italy). It stands out that in this restaurant project managers are in sight, they are responsible for: all necessary activities have been completed in the right sequence and on time; the project did not go beyond the budget; the project would meet the quality standards, etc. The study also examined an example of project caching to change the project completion time from the restaurant Pizza Duono (Italy, Rome). According to the methodology of this restaurant, on each of the critical paths the restaurant must identify one type of activity that can be subjected to crashing.

Purpose: Evaluate and compare PERT/CPM and Critical Chain Project Management (CCPM) techniques, from the Theory of Constraints (TOC), in relation to indicators of delivery time estimation and reliability in meeting established deadlines. Theoretical framework: The research is based on the time management theory established by the PERT/CPM and CCPM methods. Design/methodology/approach: This work has an experimental character, using a method of computer simulation by applying the Promodel software. A fictitious project environment managed by PERT/CPM and CCPM techniques was modeled in order to evaluate and compare their performances in terms of estimation of, and compliance with, project completion deadlines. Findings: The results obtained showed that the CCPM method proved to be more effective in reducing project completion time and meeting established deadlines. Conversely, the PERT/CPM method increased planned project completion time by 189%. Research, Practical & Social implications: Many managers assume that the best approach to project planning, especially when aiming for short and reliable deadlines, is to allocate margins of safety to each scheduled activity. This research reinforced the already widely held perception of TOC that, due to certain ordinary human behaviors, local optimizations do not guarantee, and usually adversely effect, good global results. Originality/value: There is a lack of research comparing PERT/CPM and CCPM techniques through modeling and computer simulations of project environments subjected to certain degrees of uncertainty, particularly in terms of performance variables such as those studied here. The results of this research, therefore, address this opportunity, bringing to light comparative scenarios and explanations for the different behaviors observed.

The Impact

The process of planning and project control during the execution of the construction project work is an important part of the project. Because time is limited by the project management work schedules are determined so that the leaders involved in the project should be able to anticipate changes in conditions. The failure of a project can be caused by poor planning and control are less effective, so that the project activity is not efficient. Doing so may result in delay time, declining quality, and the rising cost of implementation. Conversely, careful planning and effective control will bring the project to success.Critical path method (CPM) is one option that is right for project management to control the project completion time effective and efficient. In order to reduce the impact of delays and cost overruns of the project budget can be done with three alternative acceleration process control; (I) Addition of labor, (ii) Overtime, (iii) Subcontract. Acceleration duration is done on the works is in the critical path.

Project Completion

Between fifty to eighty percentof the projects known are not completed within the specified number of working days. Either the contractor was assessed liquidated damages or time extensions were authorized, necessitating additional manpower and / or extended working hours.The result in both cases was animmediate financial loss to the contractors; these losses were ultimately passed on to the company in general, contributing to spiraling project costs.Therefore, this paper examines and analysis data related to the project of the reactivation of line 1 for the production of iron ore concentrates of national Iron Ore Mining Company, Itakpe. Data collected involved the optimistic time, most likely and pessimistic times of completion of critical activities making up the project. This data was analyzed using the Program Evaluation and Review Technique(PERT), a MATLAB program was written to determine the critical path and the probability of project completion at a simulated time. It was found out that the project should have been completed in an optimal time of between 110 and 120 days as against the actual completion time of 180 days. The result of the simulated optimal completion time was compared to the actual completion time. Management agreed to adopt the PERT technique in future project works in the organization.
