[01607] AN INVENTORY MODEL WITH PRICE- AND STOCK-DEPENDENT DEMAND

  • Session Time & Room : 3C (Aug.23, 13:20-15:00) @D505
  • Type : Contributed Talk
  • Abstract : In this paper, we develop a multi-item inventory model with price- and stock-dependent demand and backorder. The decision variables in the model are the cycle length and the time when inventory drops to zero. The purpose of the model is minimizing the total inventory cost. Comparisons among alternative replenishment policies such as individual order, joint order or combination between these two policies are also considered. Numerical experiments and sensitivity analysis are also given.

[00224] Multi-objective multi-route STP with carbon emission and risk mitigation in Pharmaceutical Supply Chain under Pythagorean fuzzy Environment

  • Session Time & Room : 3C (Aug.23, 13:20-15:00) @D505
  • Type : Industrial Contributed Talk
  • Abstract : This research proposes multi-objective multi-route fixed-charge solid transportation problem with carbon emission and risk mitigation in Pharmaceutical Supply Chain (PSC) under trapezoidal Pythagorean fuzzy environment. A novel ranking index is proposed to convert the suggested Pythagorean fuzzy model into its deterministic version. This study develops new computational procedure to minimize the chosen factors in PSC. Thereafter the model is solved by intuitionistic fuzzy and hybrid programming. Finally, an example is included to show the effectiveness of the model.

[00557] Three dimensional laminar flow in a dividing channel

  • Session Time & Room : 3C (Aug.23, 13:20-15:00) @D505
  • Type : Contributed Talk
  • Abstract : This talk will describe a mathematical-modelling study concerned with fluid flow within a channel using asymptotic methods to study fluid behaviour on long axial length scales. Although many 3D problems can be solved through direct numerical simulations, it is generally useful to verify them with concrete analytical theory, which this study aims to do. Motivations for this research relate to providing insights into branching flows for cardiovascular vessels, industrial problems and Hele-Shaw cells.

[00885] Hybrid nanofluid of Heimenz flow over electromagnetic surface: Enhancement in thermal energy

  • Session Time & Room : 3C (Aug.23, 13:20-15:00) @D505
  • Type : Industrial Contributed Talk
  • Abstract : Over decades, the Hiemenz flow for heat transfer mechanism has gained a lot of significant consideration from engineers and researchers owing to the optimal rates of heat transfer, pressure and mass deposition near stagnation point in high speed flows. The stagnation region flows, initiated by Hiemenz [1], are very frequent and extensively adopted for modeling in considerable fields, such as micro cooling systems, extrusions with a die, continuous casting, jet impingements, and-so-forth. The novel and advanced concepts of nanofluids offer fascinating heat transfer characteristics compared to conventional heat transfer fluids. Applications of nanofluids in industries such as heat exchanging devices, cool automobile engines and welding equipment and to cool high heat-flux devices such as high power microwave tubes and high-power laser diode arrays. Hybrid nanofluids can also effectively be used for a wide variety of industries, ranging from transportation to energy production and in electronics systems like microprocessors, drug distributors to check the chemical reactions of drugs in blood, as coolants and heat exchangers for better heat transfer, as lubricators, in nuclear reactors for thermal emission and absorption, solar concentrators for absorbing much of the solar radiation, and many more. The objective of this study to improve the heat transfer rate by solving Hiemenz flow of hybrid nanofluid over an electromagnetic surface.
