Sarma en dc. The techniques used in the analysis of manpower systems are also provided.
Two models are studied in chapter 2. Model 1 is the extension of Ragavendra where maintainability of grade is considered. In model 2 we give importance to efficiency and skills of the employees by allowing multiple promotions. That is, an employee has been promoted to the next higher grade due to seniority and efficiency, whereas he is promoted to other higher grades due to efficiency only.
The promotional probabilities and recruitment vectors and cut-off levels of seniority and efficiency for promotions are found. The study of intermittently busy manpower system is studied in chapter 3.
By identifying the important random variables, busy and lean periods, the amount of crisis has been obtained in the stationary case. The asymptotic confidence limits are also obtained for the crisis. A non-Markovain model is also studied by assuming that some of the distributions are arbitrary. Various system measures have been obtained using the correlated alternating renewal process.
In chapter 4, an attempt is made to analyze impact of category and grade dependent promotion probabilities on the grade structure of hierarchical manpower systems. To be specific, we consider a multi-grade manpower system in which each grade is subdivided into several categories according to length of service in that grade. The last category of each lower grade consists of persons who have completed a specified period of service in that grade and do not get promotion. An employee in a lower grade is eligible for promotion to the most junior category of the next higher grade and the probability of promotion is dependent on the grade and category of the employee.
Un-promoted employee of a category of a lower grade will move to the next higher category of the grade in the next unit of time until he reaches the last category of the grade from where he is either promoted or leaves the system. The unit of time may be taken as a year. The movement of an employee from one category to another category is called transition.
Introduction To Manpower Planning Business Essay
New entrants to the system are allowed in the lowest category of the lowest grade. Wastages are allowed from any category of any grade and no demotions take place. The probability distribution of the state of the system is derived. The recurrence relation for the moments of the grade sizes is derived and the expected time to reach the top-most grade by a new entrant in the lowest grade is found.
A numerical example is provided to highlight the impact of category and grade dependency on the grade structure of a particular organization. Analysis of optimal promotion policy using queuing approach is studied in chapter 5.
Rostering and Task Scheduling - DTU Orbit
Queuing approach is used for the first time in Manpower systems. Various system measures have been studied and cost analysis is also studied. Numerical example illustrates the results obtained. Our concern is with control problems which arise in connection wi th a discrete time Markov chain model for a graded manpower system. In this model, the members of an organisation are classified into distinct classes. As time passes, they move from one class to another, or to the outside world, in a random way governed by fixed transition probabilities. The emphasis is, then, placed on examining means of reaching and then retaining the structure best adapted to the aims of the organisation, with the assumption that only the recruitment flows are subject to control.
Attainability and maintainability have received a great deal of attention in recent years. However, much of the work has been concerned with deterministic analysis, in the sense that average values are used in place of random variables. We adopt, instead, a stochastic approach to the study of these forms of control. We present some of the problems encountered when evaluating probabilities related to the distribution of stock numbers at different steps and we give a detailed numerical comparison of different recruitment strategies.
An iterative method is developed to compute exact values of the probabilities of attaining and maintaining a structure in one step.
