We propose a randomized search method called Stochastic Model Reference Adaptive Search (SMRAS) for solving stochastic optimization problems in situations where the objective functions cannot be evaluated exactly, but can be estimated with some noise (or uncertainty), e.g., via simulation. The method is a generalization of the recently proposed Model Reference Adaptive Search (MRAS) method for ...

An extensive review on warehouse operation planning problems is presented. The problems are classified according to the basic warehouse functions, i.e., receiving, storage, order picking, and shipping. The literature in each category is summarized with an emphasis on the characteristics of various decision support models and solution algorithms. The purpose is to provide a bridge between academ...

We describe the WordsEye Linguistics tool (WELT), a novel tool for the documentation and preservation of endangered languages. WELT is based on WordsEye (Coyne and Sproat, 2001), a text-toscene tool that automatically generates 3D scenes from written input. WELT has two modes of operation. In the first mode, English input automatically generates a picture which can be used to elicit a descripti...

Many writers have claimed that research and development (R&D) has two faces. In addition to the conventional role of stimulating innovation, R&D enhances technology transfer (absorptive capacity). We explore this idea empirically using a panel of industries across twelve OECD countries. We find R&D to be statistically and economically important in both technological catch-up and innovation. Hum...

The increase in equity prices over the 1990s has to a large degree been attributed to permanently higher productivity growth that is derived from the ‘new economy’ and related research and development (R&D) expenditures. This paper establishes a rational expectations model of technology innovations and equity prices, which shows that under plausible assumptions, productivity advances can only h...

In order to cope with the objective contradiction of worsening environmental problems and rigid demand for energy due rapid economic development, it is great significance explore technology management mode microgrid which self-used locally consumed renewable energy. this study, on basis clarifying construction goal microgrid, system designed, control consistent characteristics selected, busines...

Many writers have claimed that research and development (R&D) has two ‘faces’. In addition to the conventional role of stimulating innovation, R&D enhances technology transfer by improving the ability of firms to learn about advances in the leading edge (‘absorptive capacity’). In this paper we explore this idea empirically using a panel of industries across twelve OECD countries. We find evide...
