Correction of questions from
Picaso case
Session 1: Entering items
QUESTION1-1 The timeframes for obtaining the products (corresponding to the time of
completion of the final manufacturing step for a compound or at
supplier delivery time for raw materials is
specified independently of the batch sizes of production
or commands. For example, 3 days for ARM100. What about
Do you think? Is this consistent with a planning method?
production activities?
RESPONSE1-1 This is clearly a simplification of the lived reality.
on the ground. This simplification has an impact that can be controlled
in the case of raw material supplies, via
global negotiations with long-term suppliers. At the level
of the production activity, this rigidity, which has the advantage of
simplicity of implementation poses more problems and corresponds
manifestly one of the weaknesses of the approach
planning. Such an approximation remains justified for the
situations where waiting times in production are much longer
larger than the operational times. In this case, the size of the batches matters
relatively little actually on the duration of cycles.
Session 3: Load Posts, Ranges of
fabrication
QUESTION3-1 Where are the material consumptions specified?
RESPONSE3-1 In the nomenclatures.
QUESTION3-2 What is transfer time?
RESPONSE3-2 It is the time required to move from one operation to the next.
next.
QUESTION3-3 What is the quantity of time?
-2-
RESPONSE3-3 The quantity of time is the number of pieces completed in the time
specified machine. This allows expressing times in the form of
cadence: for example, if we enter 1 in time and 40 in the
quantity of time, this means that we produce 40 pieces per hour.
QUESTION3-4 Has it been defined at this level according to which range a given article is in?
manufactured (for example ARM100)?
RESPONSE3-4 No.
QUESTION3-7 How to assess the 'machine' costs of the different positions
cost related to the production of a batch of 100 profiles

RESPONSE374 We multiply the machine times by the quantity and add the time.

Session 6: Procedure for Calculating Needs
QUESTION6-1 Examine the curriculum plan for the ARM100 and ARM200 articles.

RESPONSE6-1 These programs are the production goals to be achieved.
The origin of needs allows us to see from which needs a
order has been generated.
QUESTION6-2 Visualize the length of the supply and production cycle
finished products ARM100 and ARM200, via the page Management of
the nomenclature set the representation page of these cycles obtained by
the buttons GRAPH and OFFSET. Approximately,
What are the delivery times for these items and what
What are the production timelines?
RESPONSE6-2 The critical supply deadlines are 10 days, which
leave a critical production lead time of 9 days, to lead to a
total cycle of 19 days.
QUESTION6-3 At this level, what is the link between the calculated production cycle in
the nomenclature pages and specified operational times in the
ranges?
ANSWER6-3 At the basic level of use, Prelude does not test consistency.
from this data.
QUESTION6-4 Examine the suggested orders for ARM100, via the list of orders.

these orders. How were the required date and the date calculated?
launch, the deadline and the cycle? Visualize the needs for components
in the Components tab. What is the range used for evaluation
the manufacturing deadlines?
RESPONSE6-4 The dates were evaluated according to classical MRP theory from
of the obtaining deadline that is set by the user in the Rules page
management(menuPlanning). The manufacturing cycle is evaluated at
the launch range support: AR.
QUESTION6-5 What is staking?
-3-
RESPONSE6-5 The scheduling of manufacturing orders with infinite capacity consists of
calculate the possible dates for the completion of operations (by
independent suppositions) based on their duration and capabilities
daily charge reports, but assuming the existence of a
infinite number of charging stations of each type. The signage
presupposes that a position will always be available to carry out a
order.
QUESTION6-6 Visualize a management page of a suggested manufacturing order
first for example) (menuPlanning, optionManagement of
suggested manufacturing orders, TABDATES). How were they
calculated the dates?
Visualize the positioning of the order over time via the button
GANTT.
RESPONSE6-6 During benchmarking, several types of dates are evaluated. The date
the earliest start of an order is equal to its launch date
(generated by the needs calculation) or on the current date if it is
later. The earliest end date of an order is equal to the date of
start at the earliest plus the sum of the durations of the operations. The date of
the deadline is equal to the date of need (last business hour,
set by the calculation of needs). The latest start date of a
order is equal to the end date at the latest minus the sum of the durations
operations. The margin is equal to the difference between the date of
start at the latest and the start date at the earliest (in hours
workable).
QUESTION6-7 Examine the margins of the OF (menu Planning, margin option)
How are the margins calculated? What can be done about it?
conclude? What are the advantages and disadvantages of having
positive margins on certain contracts? What do margins mean?
Negatives? Calculate the margin from the delay and the cycle.
RESPONSE6-7 Margin = delay - cycle. It is calculated in number of hours over the
calendar. All OFs show positive margins. They are therefore
undoubtedly achievable.
These margins are safeguards to ensure that we can comply with the
scheduled dates despite the uncertainties. Disadvantages, this leads to
generate stocks, since the orders have been launched in advance.
QUESTION6-8 Call the charges table (menuPlanning, optionTableau)

non-empty cell to view the origin of the charges. Click the button
GRAPH. What do you conclude?
RESPONSE6-8 None of the charging stations are saturated. Therefore, we have a strong chance.

QUESTION6-9 Call the workload chart (Planning menu, option
Load chart). Select the periods WEEKS.
Click on the various options offered. What do you conclude?
RESPONSE6-9 The charge graph shows significant differences in
charge between weeks or days.
