3.1 Software Requirements Specification

3.1.1 Introduction

The system addresses every aspect of crew management. Its Human Resource function tracks recruitment, terminations and re-employment, promotions and demotions, appraisals and disciplinary, personal data and occupational position, and movement history.

This chapter focuses on the specific requirements of the project. Complete specification which describes all the functionalities and process of the propose system.

This chapter also uses different UML diagram to explain specifically the process of the proposed system to make it more understandable how the user communicates with the system.

Crew Recruitment and PlanningRecruitment is the process of locating, identifying, and attracting qualified

applicants for a specific job. The result is a pool of applicants, from where the appropriate candidate can be selected. Effective recruitment results in an organization hiring employees who are skilled, experienced, and adaptable to the general corporate working culture. Recruitment is almost central to any management process, and failure in recruitment can create difficulties for any company, including an adverse effect on its profitability. In addition, it can lead to labor shortages or problems in management decision making.

Crew Management OperationCrew planning is the process of systematically reviewing Human

Resource requirements to ensure that the required numbers of the employees with the required skills are available when and where they are needed. Human Resources planning aims to achieve the optimum use of HR and to have the appropriate number and types of employees needed to meet organizational objectives. Management of shipping HR uses an efficiency factor for their activities’ planning and organization with an important social dimension. First, it’s well known that without seafarers onboard, the important contribution of shipping to the flow of international trade would not have been possible. Thus, it is essential to make sure that they are qualified enough to do their work under optimal working conditions and to keep them highly motivated. At the same time, crew efficiency is an important factor in a vessel’s operational efficiency and profitability. Therefore, the challenge for crew planners is to maximize and sustain at good level both aspects. This is not an easy task, given the many uncertainties and peculiarities of the shipping industry. The main operational difficulty is the duration of “crew employment,” which applies for short period of

Project Study 1 and 2 - Crew Management System


time. A month, few months, or a year at maximum are normal durations of the employment contracts, which mainly depends on the seafarer’s nationality and rank as well as in some cases on individuals’ preferences. Upon the expiration of the contract, there is no commitment (or at least legal obligation) either for the employee or for the employer to proceed with their professional relationship. Moreover, the availability of personnel, which depends on certain factors like illness, holidays, and career development does not allow for long-term planning.

3.1.1.3 Software Context

This EAM System is a very efficient one, which maintains the database of Asset records. And this System is less expensive and also reduces complexity. EAM has an ability to monitor, manage location, installation of hardware and software or services to be performed and status whether it is In



Use, In Storage or Out for Repair. The EAM system makes it easy for the Airline Company to manage asset and meets the organization’s needs.

There are many issues from managing the asset of the company but via help of the Enterprise Asset Management System it will keep the facilitators updated with their daily activities. Configuration, Installation, Reparation and Monitoring the daily activities related on the assets are the major concern of the airline administrative.

It Handle’s the day-to-day activities of the airline that only related in asset management and services. It’s easy to use for managing all the asset of the company, easy to access Enterprise Asset Management System. Build efficiencies with your daily asset management process by decreasing administrative tasks and data entry. From procurement’s request for new materials then waiting for approval from the asset and to the inventory for updating the records for the material’s needed.

3.1.1.4 Major Constraints

The Enterprise Asset Management System will use a Java application which requires SQL as a database to support this technology.

3.1.2 Usage Scenario

The Crew Management System project has conducted surveys of scenario research and practice, with an emphasis on the requirements engineering task within software and systems engineering. To structure the analysis, the project followed an approach which perceives an information system to comprise four interacting basic perspectives or “worlds” [Jarke et al. 1992]. As a product, an information system can be modeled as a human-machine system which provides users information or control over a subject domain (often called Universe of Discourse) which is denoted by the information objects. Users can be studied in two complementary roles: as individuals with cognitive problems of understanding, and as social organizations exploiting the information system as a communication and coordination medium to support their tasks, interests, formal roles, etc.

3.1.2.1 User Profiles

Administrator An Administrator has the responsibility for adding, editing

Crew information and change their assigned task. Crew The one who responsible in giving a service from

the passengers.



System the System refers to the hardware and software that manage and controls the application. This system accepts all that user input and user output.

The administrator can add and edit many information records after their receive the crew records from the fatigue manager so still the relationship would be one-to-many relationship.

In terms of adding a supplier only administrator has an

authorization to add a supplier. Administrator may be able to add many

suppliers. The relationship between the administrator and adding a supplier

would be one-to-many relationship.

Every user should use registered username in order to view the crew

information.

The system is using SQL therefore the systems should be properly connected to

the server to access database.

3.1.7 Validation Criteria

System validation will ensure that the system responds according to the users expectations; therefore it is important that the end users be involved in some phases of the test procedure.

3.1.7.1 Classes of tests

All the subsystems must undergo the unit testing including:

Login Adding Records Viewing Records Edited Information Viewing and Printing Reports or Reports Accessing through system will be performed by the users of the system.

3.1.7.2 Expected Software Response

The software will response if the user inputs correct username and

password to access in the system.

The software should not be capable of deleting an information record even if it’s no longer exists in the system. It should be in the status of Active or Inactive.
