1. Determine True/False: (i) The CPM method was developed primarily for the construction industry. (ii) CPM uses a certain value for project duration. (iii) A Dummy Activity always has zero duration. (iv) In a CPM arrow network, when two or more arrows begin at the same node, this means that the work must end at the same time. (v) The Forward & Backward Pass algorithms calculate EST and LFT, respectively, of all activities. (vi) The Critical Path time is defined as the shortest possible path of the network. (vii) Backward Pass Algorithm assumes the duration of the project as obtained by the Backward Pass. (viii) On the Activity-on-Arrow network, the nodes represent a logic. (ix) To draw an Activity-on-arrow network, Activities PA are needed. (x) Calculation of duration of a Project (Dij) using Average Productivity is usually a pessimistic one. (xi) If an activity has an EST equal to its LFT then it's on the Critical Path. (xii) An activity A(i, j) is a Critical Activity if E(i) = L(j). (xiii). A project always has at least one Critical Path. (xiv) Of all the floats, Independent Float always has the maximum value. (xv) If all Free Floats along a path are non-zero, then that is a Critical Path
