MESE-Next and MESE-Realtime

About MESE

MESE (Management and Economics Simulation Exercise) is a business simulator which students create virtual companies, sell products, and compete in their companies' MPI (MESE Performance Index). The simulation is period-based. In each period, a virtual company will receive their reports and do five decisions: Price of their products, production in the next period, marketing investment, capital investment, and R&D investment.

MESE was created in the 1980s. It was widely used by JA (Junior Achievement) in its course JA Economics to teach students knowledge of company management and economic environment. There is also a web-based MESE variant called JA Titan. Unfortunately, the use of MESE / JA Titan was discontinued in 2013.

MESE-Next

MESE-Next is a fan-made MESE variant. It is not a strict equivalent of MESE, but an online game based on a similar mathematical model to MESE. Players can sign up on a MESE-Next Server and compete with other players on the Internet. MESE-Next is created by hczhcz as a replacement of IMese (Internet-based MESE Platform).

Difference between MESE-Next and MESE

• MESE-Next is web-based;
• MESE-Next supports more than 8 players in the same game (32 players maximum by default);
• MESE-Next supports more game settings;
• MESE-Next provides 8p-feeling settings in any game;
• Classic MESE have paper-based reports (for MESE-Next, the reports are web pages);
• Classic MESE supports bots;
• There are some slight differences in their mathematical model;

Difference between MESE-Next and JA Titan

• MESE-Next is not a single website but a deployable web server;
• MESE-Next supports higher maximum players, higher maximum periods, and more settings;
• JA Titan supports pick-up games, and human-vs-bot games;

Difference between MESE-Next and IMese

• MESE-Next does not need a MESE executable;
• MESE-Next supports higher maximum players, and multiple games at the same time;
• IMese supports encrypted connection;
• IMese has a history analyzing and player ranking system (here is a standalone system);
• IMese only runs under x86 Windows environment;

MESE-Realtime

MESE-Realtime provides a new way to play business simulation games. Compare with MESE-Next, it runs every second without waiting for players' submissions. The typical length of a game is about 10-20 minutes, and players could change their five decisions at any time.

The Workflow

MESE-Next Engine ---+--> MESE-Next Server ---+
                   /                          \
      Database ---+              Web Server ---+--> Web Browsers
                  |                            |
                  +--> MESE-Realtime Server ---+

Server Side Requirements

The server requires all of:

• Node.js 5.10+
• MongoDB 3.0.0+
• Node.js packages: MongoDB, Express 4 & Compression, Socket.IO

MESE-Next requires:

• MESE-Next Engine binary

Installation

The server itself does not need installation.

Before running the server, you may do the following steps:

1. Clone this repository or download it;
2. Install Node.js and MongoDB;
3. Install NPM (Node.js Package Manager);
4. Install required NPM packages: mongodb, express, compression and socket.io;
5. Make sure that MESE-Next Engine is in the same directory as MESE-Next Server's, and give it execution permission (chmod +x);
6. Edit config.js if you want to change some configurations;
7. Now, you could run main.js using Node.js.
