Planning and visualization (civil engineering ) - Assignment Example developing a project using As Late as Possible (ALAP) method will make all the tasks critical tasks and hence include all tasks in the project’s critical path. In essence, this method implies that all tasks will be sent to start at a date that will not affect the dependent task but will also not leave any room for delays. For every task, the late start date is the last date the project is expected to be ready, less the duration the task is expected to complete in order to be ready. Resource leveling often involves consideration of predecessors and successors as well as a number of other constraints. Consequently, when unskilled resources are insufficient to allow start of task at its LST, a delay beyond LST may be warranted. This ensures that the existing resources are used within the task without the need for either over-allocation, or extra expenditure on unskilled labor. In essence, these delays will lead to outright extension of the project’s duration. However, where the last start date is calculated as the latest possible date for the task’s start where all its successors and predecessors are also started and ended of their last start and end dates, the project end date may remain unaltered. However, for fixed task duration, where a successor task experiences delay, the delay is fa ctored into a date in LST. Task scheduling involves resource leveling process which is helpful in resolution of the problem of resource over-allocation by delaying tasks until the assigned resources becomes available to work on it. In the absence of resource leveling, plan schedule is accomplished using information such as task plan dates, as well as constraints and dependencies of individual task items. Resource leveling introduces the question of resource availability in calculation of time. Organization benefits from avoidance of conflicts and untimely delivery. Consequently, resource leveling is a very important process. Over-allocation of resources is a major cause of
