Another insight from the beta distribution is a skew (flattening to the right), which tells us how (in most cases) our estimate is tilted towards optimism rather than the pessimistic end. This distribution captures the reality of estimation. The PERT Formula The PERT formula to calculate the P...
This problem relates to a construction project in which we wish to predict the profit (Y) using X1 (the size of the contract) and X2 (the supervisor's experience) and we care considering two models: Model I: Y=B0 + B1X1 ...
The materials used to form the pipe are as follows: Outer Layer: Polyethylene raised temperature (PE-RT) plastic coat: protects the aluminium core and allows the outer shell to be coloured without contaminating the water. Adhesive layer: interface zo...
This paper questions what network parameter-estimates really are. This follows recent papers on Parkinson's law, on the relationship with Management by Objectives, and on the historical basis on which these estimates are made. An underlying distribution is proposed that follows from these points-...

PERT(Program Evaluation and Review Technique)即计划评审技术,最早是由美国海军在计划和控制北极星导弹的研制时发展起来的。PERT技术使原先估计的、研制北极星潜艇的时间缩短了两年。 简单地说,PERT是利用网络分析制定计划以及对计划予以评价的技术。它能协调整个计划的各道工序,合理安排人力、物力、时间、资金,加速计划...

1C 1D 1H 1S is non-forcing and non invitational, promising 4=4 majors. It’s the sort of hand on which, were one 4=5 in the majors, one would pass 1H. We use xyz over 1H, so we can have 1S less than invitational, and accepting the transfer shows a minimum range opening bid,...
For each activity, make three time estimates: Optimistic time: o Pessimistic time: p Most-likely time: m Beta Distribution Assumption: The variability of the time estimates follows the beta distribution. PERT with Uncertain Activity Durations Goal: Calculate the probability that the project is ...
