I've been unhappy with our representations of resource capacity,
resource utilization, and task constraints. This proposal is intended to
inspire some thought on the subject, not to suggest a complete design.
I'd like to re-write some of the definitions given in Crawford [1]. I'll
reproduce the relevant section with my changes here.
Let t be time, B = { true, false }, and N be the set of natural numbers
including 0.
Given: A set of tasks T, a set of resources R, a capacity function
C : R x t -> N, a duration limit function L : T x N -> B, a utilization
function U : T x R x t -> N, a time constraint function W : T x t -> B,
a partial order P on T, and a deadline d.
Find: An assignment of start times S : T -> N and durations D : T -> N
satisfying the following:
1. Precedence constraints: If t1 precedes t2 in the partial order P,
then S(t1) + D(t1) <= S(t2). (Note that this is only end-start
precedence.)
2. Resource constraints: For any time x, let
running(x) = { t | S(t) <= x <= S(t) + D(t) }
Then for all times x, and all r in R,
(sum for all t in running(x) over U(t, r, x)) <= C(r, x)
3. Deadline: For all t in T,
S(t) + D(t) <= d
4. Time constraints: For all times x and all t in T,
t in running(x) implies (W(t, x) = true)
5. Duration constraints: For all t in T,
L(t, D(t)) = true
Note that, as far as I know, the only reason for the deadline constraint
is to turn this into a decision problem: "Is there a satisfying schedule
with a makespan of 20 days? Yes? How about 19 days?" I think it's
important for the formulation of the problem, but not important to the
implementation. So I'm not suggesting we need to store a project
deadline.
So the model is that all these hard pieces are just functions, either
boolean- or natural-valued. I propose this model because I know more
about functions than I do about project management, and so finding UIs
and data structures for functions seems easier to me than doing so for,
say, resource capacities.
This also precisely defines the semantics of the various kinds of
constraints.
So. Any comments? Ideas on how to represent functions to the user? Did I
miss any important constraints? Bart, do my changes make scheduling way
harder?

Scheduling." http://www.cirl.uoregon.edu/crawford/papers/albur.ps

Thanks for checking other project management software, Deren. That's really useful information. I'm not sure why you only mailed me, but I think I've covered all your points here. I'm not sure I understood what it would mean to have resource and constraint information on groups. Please tell me if this sounds right. Constraining a group is like adding that constraint to all tasks in the group. If a group must start after June 1st, and a task must start after May 1st, then the task must really start after June 1st. If another task in that group must start before April 1st, the constraints conflict and the project can't be scheduled. When a group uses a resource, effectively all tasks in the group use that resource with the same amount. If a group uses 1 hammer, and a task uses 2 hammers, that task really uses 3 hammers. Do those sound about right? You said duration can't be set on groups, because it's implicit from the tasks in the group; how about precedence? As far as implementation goes, I expect there to be a translation step between the DOM structure we use internally and the view that a scheduler sees. So if we want to do this, we can store group constraints and resource usage in obvious ways, and push that data down to tasks only when a scheduler asks for it. -- Jamey Sharp <ja...@sh...> - http://jamey.is.dreaming.org/ |

I've been thinking about how to simplify hotProject implementation, and how to support scheduling better. The only reason we're using a tree of tasks is to support grouping tasks into logical chunks, right? So here's what I propose. Let's make two types of nodes in the task tree: groups and tasks. Tasks can not have subtasks, but groups can contain both groups and tasks. The only property a group posesses is a name. I see several advantages. getElementsByTagName works. We wouldn't have to worry about it finding things from sub-tasks, because there wouldn't be any. This should dramatically simplify the code. The semantics are clear for scheduling: there is only a set of tasks, not a tree. Scheduling clearly does not need to change the structure of this tree, either. Information about start and finish dates and progress can be propagated up the tree in fairly obvious ways, without confusion due to that same data having been set higher in the tree. This would make for useful reports: the user can analyze the project at whatever level is useful. (e.g., "show me progress for all groups at depth 1".) I see one issue: user interface. Now users have to be able to request either a group or a task when adding, and a different editor (supporting only group name) has to be added for groups. The right type of editor has to be invoked depending on which kind of node is selected, when the edit button is pressed. So. Comments? Especially, Bart, does this do good things for scheduling? And everyone else, have I missed some reason that this would make your code harder, or that this would be bad for project management? -- Jamey Sharp <ja...@sh...> - http://jamey.is.dreaming.org/ |

So, there's interesting stuff on AI scheduling techniques at CIRL: http://www.cirl.uoregon.edu/research/scheduling.html Oddly enough, Bart's among the alumni there. Anyway, I'm finding "An Approach to Resource Constrained Project Scheduling", by James Crawford, a useful reference as I ponder a high-level scheduling interface for hotProject. In particular, on its first page is a formal definition of this particular scheduling problem, with all the necessary inputs and outputs. If any of you are interested in working on the scheduling aspects of hotProject, I recommend glancing through some of these papers. At least check out the "Aircraft Assembly" page: it's got pretty pictures. The only startling thing is how much of this I remember from Bart's combinatorial search class a year ago... -- Jamey Sharp <ja...@sh...> - http://jamey.is.dreaming.org/ |

OK, scheduler stuff is running now. If you want to write a scheduler with direct access to the DOM, take a look at: org.hotproject.scheduler.DummyScheduler Schedulers which use this low-level interface must have their class name listed in a file, somewhere on the class path, named META-INF/services/org.hotproject.scheduler.SchedulerProvider and must implement the SchedulerProvider interface. (But you probably want to use SingletonSchedulerProvider in this case, like DummyScheduler does.) This is because I'm using the "Service Provider" part of Sun's JAR specification: http://java.sun.com/j2se/1.3/docs/guide/jar/jar.html#Service Provider The good news is that this allows jar files containing new schedulers to be plopped onto the classpath, and those schedulers will automagically appear on the "Schedule" menu in hotProject. The bad news is now I'm relying on a non-portable package, sun.misc. (It should work on any platform with Sun's JVM, I'm guessing, but not with other vendors.) The good news is I could reproduce their code in about half an hour. I disassembled it, and it's not doing very much. Oh, yeah: DummyScheduler is the "Hello, world!" of schedulers. It doesn't actually schedule at all, it just prints a message on stdout saying it was asked to do so. Next step is to write the high-level interface as an implementation of SchedulerProvider. But if somebody wanted to modify DummyScheduler to do something amusing with the project data, I wouldn't complain. I'd also like to apply the service provider treatment to reports. That should be a half-hour job. -- Jamey Sharp <ja...@sh...> - http://jamey.is.dreaming.org/ |

Hey all, Toolbar/menu items are finally hooked up for loading Chris' newproject.xml to create a new project. As with opening an existing project, this is really slow, and there's no status indication. Sorry. I also set the Save and Save As items to be disabled under appropriate circumstances. You can look at src/org/hotproject/shell/LoadSave.java if you're interested in the details. -- Jamey Sharp <ja...@sh...> - http://jamey.is.dreaming.org/ |

the blank project file is now committed to the cvs repository, it can be found in the src/org/hotproject/xml/test section. Jamey, I'm not sure where to place this on the web site. Could let me know where you want it, or you can take care of it yourself if you feel so inclined. |

I'm having good luck with OpenOffice on this PowerPoint file. I was able to remove all of the backgrounds really quickly, and making all the fonts and layouts consistent has been pretty easy. There are quirks, though. PDF print-to-file prints PostScript just like PostScript printing does; but at least ps2pdf seems to do a good job on OpenOffice PostScript. And gv can't render the first page of the PostScript output in anything but portrait mode - though later pages are fine. Anyway, please find attached a PDF of the presentation, with a number of changes I've made. And for your amusement, here are the file sizes for this presentation in various formats (sxi is OpenOffice's native PKZipped XML format): 13853 pres.sxi 19317 pres.pdf 35260 pres.ps 41984 pres.ppt -- Jamey Sharp <ja...@sh...> - http://jamey.is.dreaming.org/ |

This may sound like a silly question, but wasn't the source code supposed to be on the CD we are giving to Warren? I checked the cd and the only thing that we have is the binary distributions and the web site mirror. I seem to remember him explicitly asked for all docs, source code, and distributions. Am I right or am I making this stuff up? ( it has been a long day and it is late ) If so we will need to burn a new disk? I can take care of that, but I suspect that Jamey might want to take care of that. If I am wrong, I have no problem burning a new one. If I could get a response tonight I would appreciate it, but I suppose we can take care of it tomorrow since Jamey has a CD-RW. Christopher |

Here's my full list. Implement as much of this as you have
time for, and as little as you like.
+ As noted, phasing is broken in both directions wrt user
requirements. Fix this, but annotate the fixes.
+ I have not checked traceability with requirements in
both directions. Someone should.
+ The spec should be traced to the design, and vice versa.
+ Section 1, "About This Document": fill it in or delete
it.
+ The stuff in 2.2, 3.x wrt attributes and resources
and classes is not clear to a casual outside user.
Preface the specification with an informal description
of the model.
+ 4.4-4.8: These attributes are obviously interdependent:
specify what happens in case of conflict.
+ 4.12: "amount of a specific resource" ... "any number of
resources". Seems to conflict with itself: needs to be
fixed.
+ 5.3-5.8: Before implementing this, try to come up with
a more general system that covers these cases.
+ 5.9: This seems like a bad idea to me. I understand the
intent, but it doesn't really fit very well into
standard models of project scheduling. The use case you
give can be treated by having driving the truck consume
person-hours, fuel, and dollars separately. I would
make this a very low priority requirement.
+ 8.8: Add 8.9, End Date Task Sort. This is often more
useful, and gives orthogonality.
+ 9.2: This is not specific and clear enough. Say what
actually is needed.
+ 10.1: The first clause is not a requirement. You have
a set of required platforms, now enumerate a set of
desired platforms. What platforms are phase 1, and what
are later phases?
+ 10.2: This is not a requirement. I don't even
understand it. Replace it with real performance
criteria, e.g. imperceptible time delay in response to
data entry, max bytes per task in representations, etc.

Just one main thing that I noticed -- the phases in the spec and the phases in the requirements still don't match. Should they? For the sake of consistency, I would say yes. However, the fact that they don't match is/was a major isssue in determining the outcome of the project, so perhaps it is a good idea to leave them as they are, and include a short but concise document that explains why the phases don't match and the controversy that followed. > > Hey, if any of you are like me, you're trying to use hevea to translate > LaTeX to HTML, and you're running the unstable distribution of Debian. > Well, hevea doesn't work with unstable's ocaml-base package, version > 3.05-1, so I had to pin that back to testing with a priority that > allowed downgrades.

Could somebody glance over the specifications to see if there's anything important I should change? Bart, it'd be especially useful if you could do this. Hey, if any of you are like me, you're trying to use hevea to translate LaTeX to HTML, and you're running the unstable distribution of Debian. Well, hevea doesn't work with unstable's ocaml-base package, version 3.05-1, so I had to pin that back to testing with a priority that allowed downgrades.

This looks really bad. A tool tip needs to be added for the text feld for entering the URI of a resource since there is no label. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=459043&aid=593253&group_id=50240 |
