The development of e-recruitment system is web-based tool used in order to reduce communication gap between job seekers and employers. E-recruitment, also known as online recruitment, is the practice of using technology and in particular Web-based resources for tasks involved with finding, attracting, assessing, interviewing and hiring new personnel. Most of the existing mode of recruitment (manual recruitment) takes much time in processing the application form, existing system will not automatically send feedback to all applicant whose meet up with the job requirement but with the help of the developed system there is reduction in time to process the application form and there is automatic feedback from the employer to the job seeker that meet up with requirement. The objective of this work is to developed an efficient e-recruitment system capable of managing all stages of the e- recruitment process, including multi-job posting, agency channel management and candidate filtering to identify the most relevant candidates. The development e-recruitment system employs 3-tier web architecture. The system consisted of design activities that produce system specifications satisfying the functional requirements that were developed in the system analysis process. A Unified Modeling Language (UML) was used to build a formal model of the university recruitment system. The Web-based University Recruitment System (WBURS) was designed to be user friendly and it is easy to navigate. A Macromedia dream wave was used in coding and developing website; SWISHmax was also used for creating graphics and animation in developing the website. Structured Query Language (SQL) was employed in creation of the database for the website and adoption of PHP (Hypertext Processor) was adopted to connect the website to a database. The performance of the developed system was evaluated by consulting three university staff and relevant information was collated through personal interviews and questionnaires was administered to the staff of those university, Human Resource Departments and other relevant professionals of these university.

With the current situation of insecurity in Nigeria and the worsening condition of Nigerian roads, there is increasing demand for air travel. This increasing demand for airline services amidst limited resources results in passenger dissatisfaction and reduction of revenue for airports and airlines. The dynamics of service demand and resource supply result in check-in issues for all the stakeholders in the commercial aviation industry. Hence, this research simulated the developed model for travelers' check-in process at the "D Wing" of the Departure Section of Murtala Muhammed International Airport (MMIA), Ikeja, using Arena Software Tool. The simulation of the developed model was carried out by varying five different configurations of the servers with respect to the baggage weighing machines and passenger profiling devices to obtain the minimum average check-in time (ACT) for the process, with each configuration undergoing 133 completions of simulation runs. The result of the experimentation revealed that the 3 × 3 × 4 configuration of servers produced the smallest ACT of 18.25 minutes. This translates to a difference of about 58 minutes from the 76.16 minutes ACT of the real system; representing about 76% improvement in the check-in time of passengers. This study contributed to knowledge by revealing that the main choke points in the MMIA check-in system occur at the baggage weighing and passenger profiling areas as against the check-in counter subsection as advanced by previous works. Furthermore, the research added value to knowledge by creating a balance between customer satisfaction and cost of operations thereby accommodating the interests of the passenger and the operator who are the two main stakeholders in the commercial aviation industry.
