The menu serves as a form of advertisement and has also been recognized as an important marketing communication tool between restaurant and consumer. Extant literature have assessed the menu item performance by using the multi-factor efficiency index. However, there is a paucity of literature focusing on the efficiency disaggregation in order to improve the performance of individual food, labor, and other resources. The aim of this study was to determine the input targets for each menu item by comparing the efficiency frontier established by all menu items in two types of restaurant chains. In order to achieve this goal, the study sought to establish the food and labor cost performance assessment model utilizing the total-factor framework combined with a slack-based measure (SBM) of efficiency in data envelopment analysis (DEA) (SBM-DEA). Resource-saving target ratios (RSTR) for panel data with 35 menu items in these two different cultural type of restaurant chains including Chinese-style and Japanese-style restaurants for twelve months were assessed in a total-factor framework. The four-quadrant analysis based on efficiency and unit profit offered different strategies to the restaurateur being studied. The empirical findings indicated that the average total-factor food cost efficiency (TFFCE) was better than the total-factor labor cost efficiency (TFLCE) in these two types of restaurants. The TFFCE (80%) and TFLCE (61%) of the Chinese-style restaurant were better than those (TFFCE (76%) and TFLCE (50%)) of the Japanese-style restaurant in the observant periods. Even though the Chinese-style restaurant had a better resource efficiency, the restaurateur was still able to improve at least 20% in terms of food cost efficiency and 39% of labor cost efficiency, respectively. Managerial discussion and future study are also discussed.

The concept of cost efficiency has become tremendously popular in data envelopment analysis (DEA) as it serves to assess a decision-making unit (DMU) in terms of producing minimum-cost outputs. A large variety of precise and imprecise models have been put forward to measure cost efficiency for the DMUs which have a role in constructing the production possibility set; yet, there’s not an extensive literature on the cost efficiency (CE) measurement for sample DMUs (SDMUs). In an effort to remedy the shortcomings of current models, herein is introduced a generalized cost efficiency model that is capable of operating in a fuzzy environment-involving different types of fuzzy numbers-while preserving the Farrell’s decomposition of cost efficiency. Moreover, to the best of our knowledge, the present paper is the first to measure cost efficiency by using vectors. Ultimately, a useful example is provided to confirm the applicability of the proposed methods.

Testing Paradigm

To reproduce colors in one system which differs from another system in terms of the color gamut, it is necessary to use a color gamut mapping process. This color gamut mapping is a method to translate a specific color from a medium (screen, digital camera, scanner, digital file, etc) into another system having a difference in gamut volume. There are different rendering intent options defined by the International Color Consortium [5] to use the different reproduction goals of the user [19]. Any rendering intent used to reproduce colors, includes profile engine decisions to do it, i.e. looking for color accuracy, vivid colors or pleasing reproduction of images. Using the same decisions on different profile engines, the final visual output can look different (more than one Just Noticeable Difference[16]) depending on the profile engine used and the color algorithms that they implement. Profile performance substantially depends on the profiler engine used to create them. Different profilers provide the user with varying levels of liberty to design a profile for their color management needs and preference. The motivation of this study is to rank the performance of various market leading profiler engines on the basis of different metrics designed specifically to report the performance of particular aspects of these profiles. The study helped us take valuable decisions regarding profile performance without any visual assessment to decide on the best profiler engine.

Main Material

Induztrialization edge and economic growth bring some consequences to the society, such as pollution or environmental damage. The responsibility is not only lies in business sector but also contributed by society and public sector-government institution as their daily operational produce some waste material. One ofmaterial use in such organization daily activities is paper. Unproper use of paper will impact on cost inefficiency, as well as environmental damage due to the main material of producing paper taken from forest.Government as public service organization mostly deals with paper in their daily administrative business. While the othersites it also encouraged to put priority on budget efficiency included in paper consumption. This study aims to describe in what extend government efficiency initiative align in it environmental concerned. Specifically this study will explore the use of paper as one of most daily resource in government office using environmental management accounting (EMA)framework. The results convey that notion on some regulation pertaining with budget efficiency in Indonesia has similarity with the spirit and the benefit provided in term of EMA application. By implementing EMA properly, government may get information on cost efficiency along with environmental sustainability.

Marginal Value

Penelitian ini menggunakan metode survei dengan melibatkan 120 Rumah Tangga Petani (RTP) yang ditentukan secara acak sederhana dari 170 RTP. Data yang dikumpulkan adalah tingkat penggunaan lahan dan pupuk urea pada setiap RTP. Alat analisis yang digunakan adalah Fungsi Produksi Cobb-Douglas dengan tujuan untuk mendapatkan tingkat elastisitas penggunaan lahan dan pupuk urea (bi). Selanjutnya untuk mengetahui tingkat efisiensi penggunaan lahan dan pupuk urea digunakan alat analisis Efficiency Index (EI). EI adalah rasio antara Marginal Value Product (MVP) dan Marginal Factor Cost (MFC). Jika EI = 1, maka tingkat penggunaan lahan dan pupuk urea efisien; jika EI > 0, tingkat penggunan lahan dan pupuk urea belum efisien; dan jika EI < 0, tingkat penggunaan lahan dan pupuk urea tidak efisien. Hasil penelitian menunjukkan bahwa penggunaan lahan dan pupuk urea dalam usahatani padi di Bau-Bau memiliki EI > 1 yang berarti bahwa tingkat penggunaan kedua faktor produksi tersebut masih kurang karena dari setiap penambahan satu unit faktor produksi tersebut akan memberikan penerimaan yang lebih besar daripada besarnya biaya yang dikeluarkan. Oleh karenanya penggunaan kedua faktor produksi tersebut belum efisien sehingga disarankan untuk ditingkatkan penggunaannya.
