Optimization Model for an Airline Crew Rostering Problem: Case of Garuda Indonesia

This paper discusses the cockpit crew rostering problem at Garuda Indonesia, taking into account a number of internal cockpit crew labor regulations. These internal labor regulations are in general more restrictive at Garuda Indonesia than at other airlines, so that modeling the cockpit crew rostering problem for Garuda Indonesia is challenging. We have derived mathematical expressions for the cockpit crew labor regulations and some technical matters. We model a non-linear integer programming for the rostering problem, using the average relative deviation of total flight time to the ideal flight time as the objective function. The optimization model have been tested for all classes of cockpit crews of Garuda Indonesia, using a simulated annealing method for solving the problem. We obtained satisfactory rosters for all crew members in a short amount of computing time. This shows that the optimization problem is well-defined

The impact of cockpit automation on crew coordination and communication. Volume 1: Overview, LOFT evaluations, error severity, and questionnaire data

The purpose was to examine, jointly, cockpit automation and social processes. Automation was varied by the choice of two radically different versions of the DC-9 series aircraft, the traditional DC-9-30, and the glass cockpit derivative, the MD-88. Airline pilot volunteers flew a mission in the simulator for these aircraft. Results show that the performance differences between the crews of the two aircraft were generally small, but where there were differences, they favored the DC-9. There were no criteria on which the MD-88 crews performed better than the DC-9 crews. Furthermore, DC-9 crews rated their own workload as lower than did the MD-88 pilots. There were no significant differences between the two aircraft types with respect to the severity of errors committed during the Line-Oriented Flight Training (LOFT) flight. The attitude questionnaires provided some interesting insights, but failed to distinguish between DC-9 and MD-88 crews

Multi-Cultural Factors in the Crew Resource Management Environment: Promoting Aviation Safety for Airline Operations

There are many reasons why Multi-cultural flight crews fail to work together effectively. This research provides a review of the history of Crew Resource Management (CRM), the CRM training classes, and the communication barriers among the flight crews. The national, organizational, and professional cultures of crew members influence flight safety. While the primary focus is on Saudi Arabian Airline, the findings can be generalized to any multicultural airline. CRM training has been shown to be efficient for both pilots and flight attendants when viewed separately, especially those flying in foreign countries. The authors address accidents which were caused as a result of the lack of communication between pilots and flight attendants. A survey was conducted of 30 pilots and 30 flight attendants employed by Saudi Arabian Airlines. The results indicated the population was aware of the importance of mixed cultural differences as useful aspects of training in areas of safety and the cooperation of crew members. Furthermore, it was revealed that good communication has significant effects on teamwork effectiveness and safety. The authors recommend that the airline should establish a joint annual CRM training class for both groups

AIR CREW TRAINING, HUMAN FACTORS AND REORGANIZING IN CASE OF IRREGULARITIES

Human resource is more and more important nowadays among the resources of a company, because output and level of services can be increased, specific cost can be reduced, and the efficiency can be better with a relative little investment in human resources. It is an important issue also according to air transport safety, since 60\% of flight accidents are because of crew errors. Human resource management includes every exercise concerning the personnel; the most important issues are procurement of suitable staff, and optimal allocation among the works. Assignment of the crew must meet several requirements. The initial optimal allocation may change by carrying out the schedule, because flights are often not performed as planned. If this happens, crew must be also re-allocated, causing as little interruption as possible

Avionics and controls research and technology

The workshop provided a forum for industry and universities to discuss the state-of-the-art, identify the technology needs and opportunities, and describe the role of NASA in avionics and controls research
