Since knowledge in expert system is vague and modified frequently, expert systems are fuzzy and dynamic systems. It is very important to design a dynamic knowledge inference framework which is adjustable according to knowledge variation as human cognition and thinking. Aiming at this object, a generalized fuzzy Petri net model is proposed in this paper, it is called adaptive fuzzy Petri net (AF...

this paper investigates the problem of just-in-time permutation flow shop scheduling with limited buffers and linear job deterioration in an uncertain environment. the fuzzy set theory is applied to describe this situation. a novel mixed-integer nonlinear program is presented to minimize the weighted sum of fuzzy earliness and tardiness penalties. due to the computational complexities, the prop...

We use language to talk about the world, and so reference is a crucial property of language. However, modeling reference is particularly difficult, as it involves both continuous and discrete aspects of language. For instance, referring expressions like "the big mug" or "it" typically contain content words ("big", "mug"), which are notoriously fuzzy or vague in their meaning, and also function ...

The problem of optimizing fund allocation in the public sector through performance based budgeting is a complex process. This paper considered only a very small part of this process, namely the final allocation of public funds through goal programming technique. While analyzing the last nine years of budget data in an R&D organization, it is inferred that there is wide gap between fund utilizat...

We present the Environmental Scenario Search Engine (ESSE), a set of algorithms and software tools for distributed querying and mining large environmental data archives. The principal requirement of the ESSE system is to allow the user to query the data in meaningful “human linguistic” terms. The mapping between human language and computer systems involves fuzzy logic. We use a data resource we...

Distributional methods have proven to excel at capturing fuzzy, graded aspects of meaning (Italy is more similar to Spain than to Germany). In contrast, it is difficult to extract the values of more specific attributes of word referents from distributional representations, attributes of the kind typically found in structured knowledge bases (Italy has 60 million inhabitants). In this paper, we ...

Pedotransfer functions (PTFs) are physical–mathematical models which allow estimating soil hydraulic properties from soil data. In the absence of direct measurements, they represent a valuable tool for providing agro-ecological models with soil input estimations, whose accuracy is currently a key issue, especially in fieldand regional-scale modelling which rely on soil information databases. Th...
