  6. A dictionary dictionary unit = a productive structure; a unit is able to perform one of the steps required to accomplish an order order = the object representing a good to be produced; an order contains technical information (the recipe describing the production steps) recipe = a sequence of steps to be executed to produce a good jES Open Foundation

  8. DW: a flexible scheme DW Units … 2 1 3 1 4 … on a toroidal space 2 1 Each unit is able to do a specific step … 5 (left and right borders and top and bottom ones are close together) 3 jES Open Foundation

  9. WD: recipes WD … of a recipe with the recipes of the orders (what to do) expressed as sequences of numbers; orders with recipes are randomly generated with different lengths and structures 1 3 2 4 5 3 4 3 5 1 1 … jES Open Foundation

  10. moving recipes DW and WD moving around among units 2 13 2 4 1 3 1 132 4 4 2 1 324 how to choose ? 1 1 3 24 5 3 lack of visibility Visibility is a metaphorical representation of trustiness and cooperation in a social network; when global visibility increases, we have more “social capital” jES Open Foundation

  11. visibility and … Visibility increases with the time (initial visibility is randomly chosen) • new units appear randomly (enterprise creation) • with strategic relationships … • … or alone visibility changes some units are dropped out jES Open Foundation

  12. … bars The left (blue) bar of each unit reports the number of waiting orders (do be done) The right (red) bar of each unit reports the number of unsent products, due to the fact that a unit able to do the required step does not exist or is not visible The down (grey) bar of each unit reports the number of consecutive clock ticks in which the unit has been idle If >maxInactivity the unit is dropped out and all unsent products are lost If >maxUnsentProducts the unit is dropped out and all unsent and waiting products are lost jES Open Foundation

  13. jES Open Foundation jES Open Foundation recipe generator or distiller recipe generator or distiller each unit owns a public matrix each unit owns a public matrix recipes recipes many levels The system uses only simple recipes containing computational steps applied to unit matrixes and to general matrixs recipe generator or distiller built in a parametric way by the Observer each unit owns a public matrix recipes recipe generator or distiller each unit owns a public matrix recipes jES Open Foundation

  16. Recipes with computations (recipes are reported in external and intermediate format) time specification: seconds computational steps 1/3 External format (remember: step, time specification, time): 1 s 1 c 1999 3 0 1 3 2 s 2 3 s 2 1 s 1 c 1998 1 0 5 s 2 1 s 1 c 1998 1 1 6 s 2 1 s 1 c 1998 1 3 7 s 2 step in recipe a step with computation: step 2, requiring 2 seconds, involves computation 1999 with 3 matrixes (those numbered 0, 1, 3 in the previous Figure) time in seconds a step with computation: step 7, requiring 2 seconds, involves computation 1998 with 1 matrix (that numbered 3 in the previous Figure) Computational steps Intermediate format (remember: each step is repeated for each unit of time): 1 2 2 -1999 3 0 1 4 1000000002 3 3 1 5 5 -1998 1 0 1000000005 1 6 6 -1998 1 1 1000000006 1 7 7 -1998 1 3 1000000007 after automatic translation, the intermediate format reports the computational processes with a trick (which can be modified, adopting an other translation in OrderDistiller): we imagine here that the computations require the time reported in their steps; so they are placed at the end of the time, followed by a 0 time step (at the intermediate format level, 0 time step are reported as ‘1000000000+step’ jES Open Foundation

  17. The Java Swarm code used by the recipes with the example code c 1998 computational steps 2/3 /** computational operations with code -1998 (a code for the checking * phase of the program * * this computational code place a number in position 0,0 of the * unique received matrix and set the status to done */ public void c1998(){ mm0=(MemoryMatrix) pendingComputationalSpecificationSet. getMemoryMatrixAddress(0); layer=pendingComputationalSpecificationSet. getOrderLayer(); mm0.setValue(layer,0,0,1.0); mm0.print(); done=true; } // end c1998 Computational steps, Java code jES Open Foundation

  18. The Java Swarm code used by the recipes with the example code c 1999 computational steps 3/3 /** computational operations with code -1999 (a code for the checking * phase of the program * * this computational code verifies position 0,0 of the three * received matrixes; only if these positions are all not empty * the code empties them and set the status to done */ public void c1999(){ mm0=(MemoryMatrix) pendingComputationalSpecificationSet. getMemoryMatrixAddress(0); mm1=(MemoryMatrix) pendingComputationalSpecificationSet. getMemoryMatrixAddress(1); mm2=(MemoryMatrix) pendingComputationalSpecificationSet. getMemoryMatrixAddress(2); layer=pendingComputationalSpecificationSet. getOrderLayer(); if(! (mm0.getEmpty(layer,0,0) || mm1.getEmpty(layer,0,0) || mm2.getEmpty(layer,0,0) ) ) { mm0.setEmpty(layer,0,0); mm1.setEmpty(layer,0,0); mm2.setEmpty(layer,0,0); done=true; } } // end c1999 Computational steps, Java code jES Open Foundation
