Hi Everyone, I have enjoyed getting some of the responses here, but I did want to make a few comments. First, this mailing list is just something that I do. It actually got started five or six years ago when Daniel Kim was trying to pull together different people doing systems thinking and system dy...

Hi Everyone, I received a note about a post graduate fellowship available to look at transportation and economy interactions in Italy that might be of interest. This is open to people living in the EU. I have included some information here. More details will be available from (I dont think this has ...

Hi Everyone, Happy new year. The list has gone quiet lately, it does that from time to time, so I wanted to post something to let you know you are still subscribed. Reminders on protocol. 1. The topics need to be related to system dynamics. 2. Strive for brevity. 3. Always be polite. 4. If you want ...

Hi Everyone, I want to make a comment on this discussion and it goes back to something stated quite innocently by someone some time back that he or she had tried to model a particular exercise but had not been able to make any headway. I do find it troubling that we are finding quick presentations t...

Hi Everyone, First, I have been seeing quite a few messages recently that seem to be intended as direct replies to the senders of messages. I dont post these messages, which saves embarassment, but I dont forward them either - they are simply lost. You should reply to the list when you want to commu...

There were a couple of late postings to the training course schedule. I managed to paste one in before the schedule was posted and I have included one below. As a reminder, if you are running workshops related to system dynamics in Europe you should send the information to Tony Gill <TonyGill@phront...

Alfred Bosshard raised the interesting question of how much it matters what form a delay takes. And someone else raised the question of time profiled delay distributions. There are, of course, some rules of thumb. The higher the order of a delay (see note below) the more phase shift - the more phase...

Hi Everyone, Someone sent me a message asking what the rules were for how the system-dynamics list is operated. Let me give the nutshell overview: The system-dynamics list is meant to increase the ability of people working in system dynamics to communicate and get information. It is maintained by Bo...

Hi Everyone, Just a reminder on some protocals. 1. Attachements are not accepted. They are destroyed during the moderation process and will never be posted. If you want to post a model email it to me directly and post a message describing the model. Models are the only type of document that should b...

The project Geoff has suggested is actually something that is done frequently as a matter of course for demographers. It is, in fact, the technique by which both current population estimates and population projections are arrived at. It is also something that is done frequently by people, such as my...

Hi Everyone, Recently, someone who posted a message to the list received a response with a executable attatchment from an unknown person. Wisely, this individual deleted the attachment. If you receive an executable attachment from anyone you do not know simply delete it. Never ever run it. It is ver...

Thanks to Geroge and George for their postings on this. The simple formulation suggested by Jack Homer via George, > Aj = [Wj*Tj / sum(Wi*Ti)] * MIN(Total time available, sum(Ti)) still suffers from the problem that if there is sufficient time available, some will get more than their Ti while others...
