Dear all I need to perform some process evaluation. Sorry for not posting data and code - I do not have any, I ask only for pointing me to correct direction. Suppose I have several connected processes P1, P2, ..., Pn. Each process takes some time and have some capacity (let say like preparing a dinner for several persons - only one stove, limited capacity of utensils, heating and cooling takes some time) and some processes can by cyclic (fry onion in pan, put it aside, in the same pan fry meat, put an onion and some water and simmer for a while...). I can prepare some oriented graph (paper/pencil) or Word or drawing programme, I can also evaluate whole process by shading spreadsheet cells but those two tasks are not connected. Is there any R package/other software suitable for simplifying or helping in such tasks? E.g. When I prepare oriented graph with capacity and time for each node is there any automatic way to transfer this graph to timeline to see how long whole process will take, where are bottlenecks or so? Thank you Petr
Search on "R package Gantt", where you will find, among others, http://cran.r-project.org/web/packages/plan/plan.pdf -- Bert On Tue, Aug 7, 2012 at 1:28 AM, Petr PIKAL <petr.pikal at precheza.cz> wrote:> Dear all > > I need to perform some process evaluation.

Thanks Bert However this package is quite simple and actually it is just only plotting routine for already prepared list. This can be done by reading appropriate file but need a step before - prepare timeline from oriented graph which I did not find yet and the only way I know is pencil/paper and manual transformation of such oriented graph to a kind of Gantt diagramme. Thank you again anyway. Maybe in some time the plan package will evolve to more complex routine.
