Project scheduling and control refers to the planning, scheduling and
control of projects, which consist of numerous activities.

Scheduling issue is a frequent task in the control of various systems
such as manufacturing processes , project management and service
system control (reservation systems, timetabling).

The management of such projects is problematic, because certain
activities must be completed in a prescribed order or sequence.

Feasibility Study:- It is done to understand if the project is worth the
time, money and energy which will be spent on it.
Ex:- Engineering Problems, Budgeting etc.

Project planning- The planning was done to build a

hotel with concrete

Financial plan- Total cost involved in the project is calculated.

In project
a schedule is
a project's milestones, activities, and deliverables, usually with
intended start and finish dates.

Those items are often estimated in terms of resource
allocation, budget and duration, linked by dependencies and
scheduled events.

Before a project schedule can be
created, the  work breakdown structure
(WBS) should be made.

Dividing complex projects to simpler and
manageable tasks is the process identified
as Work Breakdown Structure (WBS).
Usually, the project managers use this
method for simplifying the project

CPM (Critical Path Method)

For developing strategies to complete a
project in less than what would normally
be regarded as the minimum time


For determining probabilities associated
with completion times when the activity
durations are unknown

Critical Path method identifies activities that influence
in a striking character that process time duration, the
sequence of these critical activities making the
“critical path”.
The advantages of the models with CPM networks are

Require a detailed analysis of the logical structure of the
Explicitly outlines the logical links between activities,
determining the real project duration, outlines the critical
activities and those non-critical, allowing certain time
reserves with the possibility to distribute to critical activities;
The made graph keeps configuration even if changes occur
duration or deadlines;
Allow projects optimization depending on time.

PERT method allows the calculation of the average time
needed for completion of a project, identification of
critical activities and estimations of probabilities of
achieving the planned deadlines.

PERT is a probabilistic method based on beta distribution
for each time of activities and on a normal distribution
(Gauss) for the estimated amount of time, allowing the
planning and control of the execution time of the entire

Microsoft project

Microsoft Project is a project
software program,
by Microsoft,
designed to assist a project
manager in

Developing a plan
Assigning resources to tasks
Tracking progress
Managing the budge
Analysing workloads

It is considering the case of a
company, S.C Logy Bic
realizing a very complex
website that will enable a
new way of selling the
products via the internet.

For the project with deterministic activity times, crashing analysis is a
process of reducing the activity time to meet the desired completion

PERT-CPM, we solve the LP model to obtain the crashing solution.

The previous Table shows that, after performing crashing analysis the
completion time is reduced from 15 to 10.

It is a graphical tool to show the start and finish times of each

In a Gantt chart, time is measured on the horizontal axis, each
activity is listed on the vertical axis and a horizontal bar is drawn to

depict activity start, finish and duration times
In this Gantt chart, for non-critical activities, earliest start and finish
times are depicted using the blue bars, while latest start and finish
times are depicted using green bars.
Critical Activities, earliest start and finish times are depicted using
the red bars, while latest start and finish times are depicted using
pink bars.

In the projects field, path represents a sequence of adjacent activities
between milestones; it is mark by a series of lines that have their origin
in the start of the project and it clears in the end

A number of critical activities, which must be completed according to
schedule, so the project to be completed in the initial date set,
determines the critical path.

The need for providing an increased attention of these activities by
studying the risks that can occur, involves a critical path management

Execution is the part of the project which is the actual groundwork
of planning.

Controlling activities are also required for troubleshooting of
problems which were unseen or weren’t forecasted earlier.

This stage involves assessing the project results, obtaining
customer approvals, assigning project team members to new work,
closing financial accounts and conducting a post-project evaluation.
