Time-tracking software are computer programs that allows users to record time spent on tasks or projects. Time-tracking software may include time-recording software, which uses user activity monitoring to record the activities performed on a computer and the time spent on each project and task .
For example, assume that we are given a serial task which is split into four consecutive parts, whose percentages of execution time are p1 = 0.11, p2 = 0.18, p3 = 0.23, and p4 = 0.48 respectively. Then we are told that the 1st part is not sped up, so s 1 = 1 , while the 2nd part is sped up 5 times, so s 2 = 5 , the 3rd part is sped up 20 times ...
Program Evaluation and Review Technique, commonly abbreviated PERT, is a statistical tool, used in project management to analyze and represent the tasks involved in completing a given project. PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F).
CPU time (or process time) is the amount of time that a central processing unit (CPU) was used for processing instructions of a computer program or operating system. CPU time is measured in clock ticks or seconds. Sometimes it is useful to convert CPU time into a percentage of the CPU capacity, giving the CPU usage.
Longest-processing-time-first (LPT) is a greedy algorithm for job scheduling. The input to the algorithm is a set of jobs, each of which has a specific processing-time. There is also a number m specifying the number of machines that can process the jobs. The LPT algorithm works as follows:
Define the manufacturing tasks for which the standard time is to be determined. Define the task elements. These are the defined broken-down steps of the task that will be observed during the study. Since a worker is going to be observed, additional categories will likely be included as well, such as "idle", "waiting for work", and "absent".
By combining those two kinds of analysis, the tool attempts to give an upper bound on the time required to execute a given task on a given hardware platform. At the low-level, static WCET analysis is complicated by the presence of architectural features that improve the average-case performance of the processor : instruction/data caches ...
The project has two critical paths: activities B and C, or A, D, and F – giving a minimum project time of 7 months with fast tracking. Activity E is sub-critical, and has a float of 1 month. The critical path method ( CPM ), or critical path analysis ( CPA ), is an algorithm for scheduling a set of project activities. [ 1 ]
