Q

JIT

A

Just-in-time strategy is an inventory management method, in which materials are received by suppliers only as they are needed, in order to lower inventory holding costs and increase inventory turnover.. This can be achieved when we have perfect information, which is not possible, so that’s why companies hold Safety Stock, which acts as a buffer for the lack of efficiency.

Q

Bullwhip effect

A

This happens when information about the demand for a product gets distorted as it passes through the supply chain. Small change in demand gets magnified, which leads to exess inventory.

22
Q

Management Information Systems

Study These Flashcards
A
  • serve middle managers
  • answer routine questions with predefined procedures to get to an answer
  • little analytical capability
  • provide reports on firm performance based on TPS
23
Q

Decision Support System

Study These Flashcards
A
  • serve middle managers
  • can use external resources as well as MIS/TPS
  • support non-routine decision making
24
Executive Support System
- support senior management - non-routine decision makinh, requires judgement, evaluation and insight
25
Data warehouses
Collect and store data from transactional systems across the organization. Data is consolidated and standardized, but can't be altered. These serve as a tool for querying, analysis and reporting.
26
Data marts
Are subsets of data stored in data warehouses: - contain a highly focused proportion of the organization's data - designed to support a specific business problem/challenge on a specific population of users.
27
Data lakes
Centralized repository that allows you to store structured and unstructured data at any scale.
28
Contemporary business intelligence infrastructure
Combines "traditional" data warehouse solutions with data lakes to integrate unstructured data and/or external data and/or large structured data sets.
29
What do database, data warehouse, data marts use as input?
Operational systems like TPS.
30
What is the output of databases?
Business intelligence tools, analytical systems.
31
What are business intelligence tools?
Tools for consolidating, analysing, accessing data to support organizational decison-making.
32
Online analytical processing
OLAP: transaction-level data from relational databases is aggregated and summarized.
33
Where are the results of analysis from OLAP stored?
They are stored in special databases called data cubes, which structure results across multiple dimensions. (Time, Place, Product)
34
Data Mining
The use of special algorithms to identify hidden patterns in and to fit models to large data sets.
35
Association
Certain atrribute values that frequently occur together in a data set. (enables vendors to tailor discounts and optimize product location)
36
Central concpets on association
1. Support x(X) is the fraction of transactions that contain a certain set of items X. 2. Confidence c(X->Y) is the fraction of transactions that contain Y amongst the transactions that contain X.
37
Big Data
1. Volume: The simple size of a dataset that needs to be processed; 2. Velocity: The speed with which new data is generated and needs to be processed; 3. Variety: The different formats & features of data that need to be processed (relational databases, documents, photos, videos, spatial & temporal aspects); 4. Veracity: The reliability of the data (user-generated content, such as restaurant reviews, but also imprecisions in measurements, such as GPS positions).
38
Analytics
Analytics applies classical statistics and AI to derive actionable insight from big data. e.g: neural networks replicate the basic functions of the human brain to predict outcome
39
Neural networks
- Are feed historic data sets on the outcome of interest or other variables
40
What did Siemens implement and how>
Implemented Celonis' Business Mining software. - analyses data in enterprise application event log to predict bottlenecks and other inefficiencies e.g: using special algorithms it can predict which orders will be late based on historical outcomes of Siemens - previously individual supervisors were responsible for one process making it difficult to understand which processes were affected by one process - organisational resistance to process mining from long-term managers
41
Types of decisions
- unstructured decisions: decision-maker must provide judgement, evaluation and insight on the decision. no well-understood procedure on makin them - strctured: repetitive and routine, definite procedure - semi-structured: only part of the problem has a clear-cut answer provided by an acceppted procedure
