A Hawk-Dove game in kleptoparasitic populations

Kleptoparasitism, the parasitism by theft, is a widespread biological phenomenon. In this paper we extend earlier models to investigate a population of conspecifics involved in foraging and, potentially, kleptoparasitism. We assume that the population is composed of two types of individuals, Hawks and Doves. The types differ according to their strategic choices when faced with an opportunity to steal and to resist a challenge. Hawks use every opportunity to steal and they resist all challenges. Doves never resist and never steal. The fitness of each type of individual depends upon various natural parameters, for example food density, the handling time of a food item, density of the population, as well as the duration of potential fights over the food. We find the Evolutionarily Stable States (ESSs) for all arameter combinations and show that there are three possible ESSs, pure Hawks, pure Doves, and a mixed population of Hawks and Doves. We show that for any set of parameter values there is exactly one ESS. We further investigate the relationship between our findings and the classical Hawk-Dove game as defined in Maynard Smith 1982. We also show how our model extends the classical on

Information System Ordering Online Restaurant Menu at Hover Cafe

The rapid development of technology requires every business person to upgrade his technology to more sophisticated. Many business people have upgraded their systems to be computerized and even online, one of the business people is in the culinary field. The culinary field which is meant for example is the cafe One thing that can support the quality of ordering in a cafe is the ordering process. In the hover cafe the menu ordering system is still conventional, using a menu book. This of course can be a problem because the menu book used can be damaged or lost so that it can slow down the ordering process, not to mention if the customer requests additional orders, the waiter must come to the customer's table to record additional orders again. The method used in this research is the method of data collection, the method of observation, the method of interviewing, and the method of literature study conducted to obtain accurate data. Then the data are analyzed with SWOT to find out the company's weaknesses and strengths. In describing the flow of the system using UML (Unified Modeling Language) and PHP (Hypertext Preprocessor) as a programming language with a MySQL database as a database. Therefore we need a ordering media that utilizes information technology as a medium for selecting food and beverage (E-Menu) which can provide information about order menu details to facilitate customers in making and ordering food or beverage menus

Information System Design Reminder Inventory Control at PT Nuansa Timur Lestari

The current information needs in the business world to be very important in determining the progress of a company. A good activity on a single company or technology is also determined by the available information. PT Lestari Eastern Nuances is a company engaged in the restaurant. The logging system supplies the raw materials of food are running currently still using Microsoft Excel to record incoming and outgoingraw food. The current running system still has many flaws and weaknesses as it takes quite a long time to figure out the amount of supplies of goods raw materials because an admin shed have to calculate the physical stock quantities directly, the occurrence of the difference in the number of requests the raw material with raw material expenses due to miscalculations by admin warehouse, takes a long time to make a request and expense report raw materials causing the company's performance be hampered, the absence of a reminder to remind Admins about the number of warehouse stock of raw materials so that when the raw materials needed by the chef stock no. Based on existing problems then needed a system to help the admin staff stock in managing demand and pengerluaran raw material so that it doesn't happen the difference in stocks of raw materials. The system will be created using the PHP programming language and the Mysql database, the method of analysis PIECES and using a systems development method in System Development Life Cycle (SDLC). &nbsp

Design Information System Stock Inventory to Manage Data of Goods (Case Study: PT Monier)

Application of information system on the inventory will provide many benefits for the company in developing company in order to improve the company's performance become more effective and efficient. This research was conducted at manufacturing companies, to know overall about inventory items in the company. The purpose of this research is to find out the effectiveness of the inventory as a resource physical economy that needs to be held and maintained in order to support the process booking goods and sales in progress PT Monier. PT Monier is as a company manufacturers concrete roofing materials with the production system where the process for creating objects with cross-section of fixed. The methods of analysis used is descriptive data analysis method. Engineering data collection with do the observations to the company, conducting interviews, and route the study library with books, the literary, the materials gained during lectures relevant to the problems examined. Research results shows that the control of inventory items It often happens booking of the goods to the supplier in excess inventory and the shortage of supplies. Due to the lack of regard for the State of inventory items. Inventory data input errors often occur more than once for similar goods give rise to errors in reporting. Then the author here attempted to analyze the problems against information systems inventory items and to find solutions to the fore of the existing problems by fixing a system that is less than optimal. Keywords : Information Systems, Effectiveness, Inventory Item
