چکیده

In this paper, we show that the notion of most regular word in the language formed by all of the words containing a xed number of each letter of an alphabet can be applied to nd the optimal resource allocation policy of the generic system composed by two processes sharing a resource. This system will be modeled as a Petri net. This result can be partially generalized to non periodic allocation sequences and non rational frequencies. For N processes sharing a resource, we show that no such optimal sequence exists. In this case, we give an heuristic to nd a good allocation sequence. S equence optimale d'allocations pour deux processus partageant une ressource R esum e : Dans cet article nous montrons que la notion de mot le plus r egulier dans le language form e de tous les mots qui contiennent un nombre xe de chaque lettre de l'alphabet permet de trouver la politique d'allocation optimale d'un syst eme compos e de deux processus qui partagent une ressource avec des fr equences impos ees; ce syst eme etant mod elis e sous forme de r esau de Petri. Le r esulat peut ^ etre partiellement g en eralis e a des s equences non p eriodiques ou non rationnelles. Pour N processus partageant la m^ eme ressource, une telle s equence optimale n'existe pas et nous donnons alors une heuristique pour trouver une bonne s equence.

Allocation sequences of two processes sharing a resource

We study a Petri net model of a system composed of two processes sharing a resource. Conflicts may occur over the usage of the shared resource, thus making the system nondeterministic. Therefore, in the context of minimax algebra, it cannot be formulated as a linear system in order to compute its performance measures. However, if the sequence by which the resource is allocated to the two proces...

OPTIMAL RESOURCE ALLOCATION IN DEA WITH INTEGER VARIABLES

Resource allocation and optimal leveling are among the top challenges in project management. This paper presents a DEA-based procedure for determining an optimal level of inputs to produce a fixed level of outputs. To achieve this goal, we assume that the levels of outputs can be forecasted in the next season and the procedure will determine optimal level of inputs for all DMUs. Such as some of...

Jointly power and bandwidth allocation for a heterogeneous satellite network

Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...

Introducing New Priority Setting and Resource Allocation Processes in a Canadian Healthcare Organization: A Case Study Analysis Informed by Multiple Streams Theory

Background In this article, we analyze one case instance of how proposals for change to the priority setting and resource allocation (PSRA) processes at a Canadian healthcare institution reached the decision agenda of the organization’s senior leadership. We adopt key concepts from an established policy studies framework – Kingdon’s multiple streams theory – to inform our analysis.   Methods Tw...
