The Future

Production of the aircraft becomes very important to facilitate many passengers of aircraft in Indonesia in the future. The design of a very complex aircraft requires proper project management. This study aims to perform the best scheduling project of empennage structure design of Indonesia’s aircraft with limited resources. Critical Path Method (CPM) is used to schedule the project based on activity and resource. CPM scheduling results in completion time for activity data for 400 working days. CPM scheduling after assigning human resources results in a longer completion time for 1023.47 working days. CPM scheduling is carried out by reallocating of human resources to produce a shorter completion time, and it results in completion time for 955 working days.

As an archipelagic country, Indonesia has high needs for its aviation development. About 270 million people are predicted to fly from and within Indonesia in 2034, which is three times larger than current market conditions. Due to the complexity of aircraft development projects, management of a well-designed Indonesian aircraft design project needs to be implemented. This research aims to analyze the scheduling of aircraft wing structure design project made in Indonesia. Critical Path Method (CPM) and Resource-Constrained Project Scheduling (RCPS) are used to get better scheduling with a shorter duration to complete the project. Results from resource allocation using RCPS can yield a shorter project duration (730 working days) compared to the company’s normal resource allocation (950 working days).

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.

An interdisciplinary design project was conducted with students in the mechanical engineering and architecture departments at the University of Idaho. In order to offer the multidisciplinary design experience within the available bandwidth of instructors, the project was structured around and integrated into existing courses and resources. Past interdisciplinary product design courses have shown the value of interdisciplinary work in the professional development of students in addition to being effective at developing innovative new products. Descriptions of these courses provide insights on conducting them with regards to team structure, course structure, design process, and other topics. This paper summarizes observations reported from students and instructors involved in this project. Observations highlight challenges in project management, examples of cultural differences between disciplines, approaches to design, specifics of project ownership, and perceptions of level of detail in work products. Based on those observations, recommendations are made to develop and deploy a design process that facilitates the strengths of both disciplines and enables mentor guided project management. In addition, these recommendations will help establish a team culture and work setting that does not violate the culture of either discipline while enabling joint decision making, and address directly the impacts of a domain biased product as the design project focus.

Along with the industrial competition nowaydays, an exact and strategic planning is highly required particulary for project. There are alot of tasks and activities within, which need to be broken down, in this term for its time line. Every success and failure is caused by raw palnning. The obyective of this research is to find efective time needed to complete a project. Method used are Critical Path Method (CPM) , Program Evaluation and Review Technique (PERT), andGantt Chart.

This articles aims to research the special maintenance vehicle so as to optimize its resource allocation in operation, which belongs to the issue of fixed completion time-resource levelling. It makes analysis on the operation deployment process, critical path and procedure of the truck based on the RLP problem solving algorithm, and makes optimization allocation to the scheme by using genetic algorithm. The new allocation scheme after the optimization can increase the efficiency by 12.5% and realize the reasonable allocation of human resources.

Critical Chain Project Management (CCPM) provided a tangible progress to the Project Management Body of Knowledge. The critical chain project management (CCPM) differs from the traditional Critical Path Method (CPM) which includes never changing resource dependencies. CCPM improves the project plan by aggregating uncertainty into buffers at the end of activity paths. In this research, one hundred twenty random projects were generated and analyzed using Microsoft Project software according to the traditional CPM and the CCPM once using the sum of squares (SSQ) method and another using the cut & past (C&PM) method. CCPM-SSQ method revealed an average savings of 13% and 43% in duration and cost, with a standard deviation of 21 and 11 for duration and cost respectively. While the CCPM-C&PM method revealed an average overestimation of about 2% in duration and 43% savings in cost, with a standard deviation of 25 and 11 for duration and cost respectively.

Project Management Information System

PT. Pakarti Tirtoagung is one of the companies engaged in construction services in Indonesia, in the scope of gas and petroleum. To facilitate the company in carrying out the project implementation process and monitoring the progress of the project, a special computerized system is needed.Looking at the system that runs on the company, there is no specific system support, which has several obstacles, among others in making schedule project, errors in recording data and presenting project progress reports because project progress was not monitored, completion of projects that are not in accordance with time schedules, etc. Of the several obstacles encountered, it becomes an interesting discussion to looking for solutions that can minimize obstacles and even risks that will occur as a result of these constraints. For that it was made Analysis And Design Of Web-Based Project Management Information System Using Critical Path Method (CPM) Method On Pt. Pakarti Tirtoagung. Using the CPM method for help planning activities to project development. Based on the results of the questionnaire that was distributed to 10 (ten) respondents and after processing the results 58% of respondents felt agree and 38% strongly agree that the system can present information about the ongoing project, monitoring the project and presenting a project progress report .

This paper deals with an analysis of Critical Path Method (CPM) and Programme Evaluation Review Technique (PERT) in Project Network. Here, we solve the PERT and CPM methodology using intervals and we determine the critical path and project duration of the network. We can also convert the fuzzy parameters (triangular and trapezoidal fuzzy numbers) into intervals using α − cuts. After which, we calculate the project duration and critical path. To illustrate this, numerical examples are provided.
