I am studying the linux process scheduler but I can not figure out how to make the Gantt chart for this situation:
Process | Arrival | Burst Time | Sched. Class | RT Priority | RT Quantum | Nice
P1 | 0 | 19 | TS | 0 | | -5
P2 | 7 | 5 | RT-RR | 2 | 5 |
P3 | 11 | 14 | RT-FCFS | 4 | |
P4 | 13 | 4 | TS | 0 | | -5
Can anyone help me please?
For display this information from the table in Ganntt chart you can use just Excel. That is the example of how do it with Excel 2010

I have a question on the Mathematics Stack Exchange site where I ask about generating an exponential regression equation.
One of the answers provides a mathematical solution to my problem. The solution is written in mathematical notation:
Unfortunately, I'm not a math wiz, and I'm having trouble translating the mathematical notation to Microsoft Excel syntax.
What would the math look like in Excel?

I can verify that your formula for a translates as follows into Excel:
=SUMPRODUCT(E2:E22,F2:F22)/SUMSQ(E2:E22)
where my E2:E22 is just your x and my F2:F22 is ln(21-y). It gives the same answer, 0.147233112, as doing an exponential fit and forcing the intercept to be zero (which corresponds to setting b=1 in
y-21=b*exp(ax)
as you can verify by taking logs).
The formula quoted is the same as the one mentioned here under Simple linear regression without the intercept term (single regressor)
So this begs the question of whether b should, in fact, be equal to 1 and this is outside the scope of the question.
I am working in Excel 2016. I am trying to figure out how many projects I have that have not had any part of it started. For instance if my project id is 203784 and it has 3 parts to it where 2 are Complete and 1 was Not Started. I would not want to count that. If the project had 3 parts and 2 were Not Started 1 was assigned. I would want to count that as 1. Thank you in advance you your assistance.
+----+------------+------------------+-------------+
| | A | B | C |
+----+------------+------------------+-------------+
| 1 | Project ID | Position | Status |
| 2 | 203784 | Staff | Complete |
| 3 | 203784 | Staff | Complete |
| 4 | 203784 | Staff | Not Started |
| 5 | 203785 | Maintenance | Complete |
| 6 | 203785 | Maintenance | In Progress |
| 7 | 203786 | Grounds | Complete |
| 8 | 203787 | Nurse | Complete |
| 9 | 203788 | Teacher | Complete |
| 10 | 203788 | Teacher | Complete |
| 11 | 203788 | Teacher | Complete |
| 12 | 203789 | Transportation | Complete |
| 13 | 203789 | Transportation | Complete |
| 14 | 203789 | Transportation | Complete |
| 15 | 203790 | Evacuation | Complete |
| 16 | 203790 | Evacuation | Complete |
| 17 | 203791 | Implementation | Complete |
| 18 | 203792 | Knowledge Base | Not Started |
| 19 | 203792 | Knowledge Base | Not Started |
| 20 | 203793 | Janitor | Not Started |
| 21 | 203794 | Public Relations | In Progress |
| 22 | 203795 | HR | Complete |
| 23 | 203796 | Admin | Complete |
+----+------------+------------------+-------------+
In this example. I would only want the count to show a total of 2. For project numbers 203792 and 203793.
One way would be to add a column (say Count) populated as:
=COUNTIFS(A:A,A2,C:C,"Complete")+COUNTIFS(A:A,A2,C:C,"In Progress")
and then create a PivotTable with Count as Filters and Project ID for Rows. Select 0 for the filter.
I want to compose sales table for purchased and sold items to see total profit. It's easy to do when items are purchased and sold individually or as a lot. But how to handle situation when one buys collection of items and sells them one by one. For example, I buy a collection (C) of a hammer and a screwdriver and sell tools separately. If I would enter data into simple table as in the image, I would get wrong profit result.
When there are only two items, I could divide their purchase price randomly, but when there are many items and not all of them are yet sold, I can't easily see if this collection already made profit or not.
I expect correct output of profit. In this case collection cost was 10 and selling price of all collection items was 13. Thus it should show profit of 3, not loss of -7. I was thinking of adding 2 new column, like IsCollection, CollectionID. Then derive a formula, which would use either simple subtraction or would check price of a whole collection and subtract it from the sum of items that belong to that collection. Deriving such formula is another question... But maybe there is an easier way of accomplishing the same
I added a column COLLECTION to identify item who belong to a collection.
Then I used SUMIF to sum sell price for items which belong at the same collection.
Then I used IF in Profit column to use summed sell price or single sell price.
You need to define in some formula a range of cell (see below).
Problem: you can't add profit values to obtain Total profit.
I used opencalc (but it should be almost the same in Excel).
Content of
SUM_COLL (row2):
=SUMIF($A$1:$A$22;"="&A2;$D$1:$D$22)
SUM_COLL (row3):
=SUMIF($A$1:$A$22;"="&A3;$D$1:$D$22)
and so on.
Profit (row2):
=IF(A2<>"";E2-C2;D2-C2)
Profit (row3):
=IF(A3<>"";E3-C3;D3-C3)
+------------+-----------+-------------+------------+----------+--------+

Update:
I added two more column to make Profit summable:
COUNT_COLL (row2):
=COUNTIF($A$1:$A$22;"="&A2)
COUNT_COLL (row3):
=COUNTIF($A$1:$A$22;"="&A3)
Profit_SUMMABLE (row2)

I have a question in Excel and need your help!
I can do this if it was static problem but I need my end result to adjust to my input in the table because the year sometimes the year finishes sooner or later or is different or the number of activities vary.
Initial table (It always go in chronological order and it only has 1 or nothing. (I put 0 there because I wanted to put space and didn't know how to do it. also Number of activities may vary)
+----------------+------+------+------+------+------+------+
| year | 2016 | 2016 | 2016 | 2017 | 2017 | 2017 |
+----------------+------+------+------+------+------+------+
| month calendar | 10 | 11 | 12 | 1 | 2 | 3 |
| month project | 1 | 2 | 3 | 4 | 5 | 6 |
| Activity 1 | 1 | 1 | 0 | 0 | 0 | 0 |
| Activity 2 | 0 | 0 | 1 | 1 | 1 | 1 |
| Activity 3 | 0 | 0 | 0 | 1 | 1 | 0 |
| Activity 4 | 0 | 1 | 1 | 0 | 0 | 0 |
| Activity 5 | 1 | 1 | 1 | 1 | 1 | 1 |
+----------------+------+------+------+------+------+------+
I want in another sheet
+---------------+------------+------------+------------+------------+
| Activity year | 2016 | | | |
| | | | | |
| Activity 1 | Activity 2 | Activity 3 | Activity 4 | Activity 5 |
| 25,0% | 12,5% | 0,0% | 25,0% | 37,5% |
| | | | | |
| Activity year | 2017 | | | |
| | | | | |
| Activity 1 | Activity 2 | Activity 3 | Activity 4 | Activity 5 |
| 0,0% | 37,5% | 25,0% | 0,0% | 37,5% |
+---------------+------------+------------+------------+------------+
Now imagine that in the "another sheet" I have nothing and I want the result to adjust to the initial table. How can I do this?
Sorry for bad editing but I can't do better.
Any help is good thank you, I answer any question you might have.
I'm going to add something that is related to this and I also need. I need a formula to get the number of different activities per year that happen at least once for my calculations later. In this case it would be a formula for 2016 which the result is 4 and 2017 is 3.
I have a file that has data stored in it the following way (weekly data example)
+----------+----------+----------+----------+----------+----------+
| | WK1 | WK2 | WK3 | WK4 | WK5 |
+----------+----------+----------+----------+----------+----------+
| DT Begin | 29.12.14 | 05.01.15 | 12.01.15 | 19.01.15 | 26.01.15 |
| DT End | 04.01.15 | 11.01.15 | 18.01.15 | 25.01.15 | 01.02.15 |
| XData | 50 | 10 | 10 | 10 | 50 |
+----------+----------+----------+----------+----------+----------+
My problem ist to aggregate the XData on a monthly basis. For that I want to break the data down for days and then calculate the average.
Edit: I changed the table as it was not clear what I meant. This averages to ((50*4)+(10*21)+(5*50))/31 = 22.90
+------------+-------+
| Date | Value |

| 30.01.2015 | 50 |
| 31.01.2015 | 50 |
+------------+-------+
| Average | 22.90 |
+------------+-------+
After having done this calculation I want to summarize the data as follows for the entire year:
+-------+-------+-------+------+------+
| | Jan | Feb | Mar | ... |
+-------+-------+-------+------+------+
| XData | 22.90 | 22.00 | 23.1 | ... |
+-------+-------+-------+------+------+
Being a newbie in Excel VBA, I have extreme trouble doing this.
I know how to get to the value of a cell (Range.Value) but not how to find data in a particular week (as WK1 is there for 2014 as well) Range.Find with a date other than the one in the cell itself does not seem to work.
Whar I am asking for is a way to approach this problem. My particular difficulties are to:
Find the data in the worksheet
split the week values into day values (see table above)
Copy the data or hold it in some sort of data structure
calculate the average (this should be ease then)
fill in the data on a monthly basis
As you can see, I have trouble even getting started - any hints would be greatly appreciated. Maybe I'm thinking of this entirely too complicated? Thank you!
