Local Zika virus transmission in the United States involving one or both of the known vector species, Aedes aegypti and Ae. albopictus, is of major concern. To assist efforts to anticipate the risks of transmission, we developed an Excel spreadsheet tool that uses vector and virus temperature thresholds, remotely sensed maximum temperature, and habitat suitability models to answer the questions...

In this research we model a job shop that produces a set of discrete parts in a make-to-stock setting. The intent of the research is to develop a planning model to determine the optimal operating tactics that minimize the relevant manufacturing costs subject to workload variability and capacity limits. We model the interplay of three key components in the job shop, namely, the production freque...

Ma már szinte nincs olyan szervezet, amelynek számítógépén ne lenne táblázatkezelő. A táblázatkezelő egyfajta döntéstámogató rendszernek tekinthető. Jelen cikk célja áttekinteni a Microsoft Excel 365 írásakor aktuális változatában elérhető fontos szolgáltatásokat, amelyek egy szervezet vezetője számára hasznosnak bizonyulhatnak döntési folyamat során. Az alapesetben is kínál adatmanipulációs al...

Rad je zasnovan na kalendaru trka Formule 1 i geografskoj lokaciji mesta za velike nagrade. Optimizacija obavljena više načina, pomoću Excel Solvera programima napisanim u Matlabu. Solver se zasniva na: ispitivanju mogućih rešenja uzimajući obzir ograničenja, a zatim odabiranju onog koje najviše odgovara. Prvi program napisan Matlabu koristi metode su korišćene genetskom algoritmu, kao što sele...

Optimization means using resources and existing technology at the best possible way. Better planning and its execution results in optimization of many problems. Quantitative models and mathematical tools such as linear programming allows for better result. We can use modern computing equipment for this purpose. Nowadays various problems of operational planning for transportation problems are so...

In this paper a knowledge-based clustered partitioning technique is developed for determining reliability index and failure probability of rock wedge. Here, the a reliability index is analyzed and the optimization is carried out using a knowledge-based clustered partitioning (KCP) technique. The reliability index computed with this KCP technique is compared with those using other approaches suc...

The objective of this present study was to introduce a simple, easily understood method for carrying out non-linear regression analysis based on user input functions. While it is relatively straightforward to fit data with simple functions such as linear or logarithmic functions, fitting data with more complicated non-linear functions is more difficult. Commercial specialist programmes are avai...

Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) are two common sexually transmitted diseases among women in the United States. Publicly funded programs usually do not have enough money to screen and treat all patients. Therefore, the authors propose a new resource allocation model to assist clinical managers to make decisions on identifying at-risk population groups, as well as select...

The problem of assembling of two mating parts is considered. Making use of the probability distributions of the bore and shaft, and the specifications on the fit between them, it is desired to define the dimensions of separate groups for the bore and for the shaft that these parts can be placed in, such that the specifications on the fit when parts in these groups are assembled will be met with...
