What the IE Licensure and FE Industrial Exam Cover

Industrial engineering exams are heavily quantitative, with most questions requiring formula application and numerical calculation. Here is a detailed breakdown of every major content area you need to master.

Operations Research and Optimization

Linear programming (LP) is one of the most tested OR topics. You must be able to solve two-variable problems graphically (identify feasible region, find corner points, evaluate objective function) and understand the simplex method conceptually. Sensitivity analysis questions test shadow price (the marginal value of relaxing a binding constraint) and ranging (how much an objective coefficient or RHS value can change without changing the optimal basis). Transportation and assignment problems are special LP structures solved by the northwest corner method, Vogel's approximation, or MODI method. Network models include CPM — you must calculate early start, early finish, late start, late finish, and total float for each activity; the critical path has zero total float. PERT uses three-time estimates (optimistic a, most likely m, pessimistic b) to calculate expected activity time t_e = (a + 4m + b)/6 and variance σ² = ((b−a)/6)². Queuing theory for the M/M/1 model: arrival rate λ, service rate μ, utilization ρ = λ/μ (must be less than 1 for stability), average number in system L = ρ/(1−ρ), average time in system W = L/λ, average number in queue L_q = ρ²/(1−ρ), average wait in queue W_q = L_q/λ. Monte Carlo simulation uses random numbers mapped to a probability distribution to simulate system behavior over time.

Manufacturing Systems and Quality

Statistical process control requires mastery of control chart types: X-bar and R charts for variable data (subgroup mean and range), p-charts for proportion nonconforming, and c-charts for count of defects per unit. Process capability indices: Cp = (USL − LSL) / 6σ measures the spread of the process relative to the specification width without regard to centering; Cpk = min[(USL − μ)/3σ, (μ − LSL)/3σ] adjusts for process mean offset. A Cp and Cpk both ≥ 1.33 is generally considered capable. OC (operating characteristic) curves display the probability of lot acceptance as a function of incoming quality. Acceptance sampling plans specify sample size n and acceptance number c; AQL (acceptable quality level) and LTPD (lot tolerance percent defective) define the producer's and consumer's risk points on the OC curve. FMEA (Failure Mode and Effects Analysis) assigns severity (1–10), occurrence (1–10), and detection (1–10) ratings to each failure mode; RPN = Severity × Occurrence × Detection, with higher RPN indicating higher priority for corrective action. Plant layout types: process layout groups similar equipment (flexible, high WIP); product layout arranges equipment in operation sequence (efficient, low flexibility); fixed position layout brings workers to the product (large/heavy items); cellular layout groups dissimilar machines to complete a family of parts (Group Technology). Material handling equipment selection considers unit load, path type, and throughput requirements.

Work Systems and Human Factors

Time study procedure: observe and time several cycles of each work element, apply a performance rating factor to get normal time (Normal Time = Observed Time × Rating Factor), then add allowances for personal needs, fatigue, and unavoidable delays to get standard time (Standard Time = Normal Time × (1 + Allowance Fraction)). Predetermined motion time systems (PMTS) such as MTM-1 (Methods-Time Measurement) assign standard times to fundamental hand motions without direct observation. Work sampling uses random-interval observations to estimate the proportion of time spent on various activities; required sample size is calculated from p (estimated proportion), z (confidence level z-score), and e (acceptable error). Learning curve theory: as cumulative production doubles, unit time decreases by a constant percentage. The unit time for the nth unit is T_n = T_1 × n^b, where b = log(learning rate) / log(2) and learning rate is expressed as a decimal (e.g., 0.80 for an 80% learning curve). Ergonomics applies anthropometric data to workstation design; the NIOSH lifting equation calculates the recommended weight limit (RWL) from load constant and six task multipliers, and the lifting index (LI = Actual Load / RWL) — LI > 1 indicates elevated musculoskeletal risk.

Engineering Economics

Present worth analysis converts all cash flows to time zero using P = F(P/F, i%, n) and P = A(P/A, i%, n) factors. Annual worth analysis converts all cash flows to a uniform annual series. Rate of return analysis finds the interest rate that sets NPW = 0. Payback period is the time to recover the initial investment from net cash flows, ignoring time value of money. Depreciation methods tested include straight-line (equal annual charge), MACRS (Modified Accelerated Cost Recovery System — used for US tax purposes, uses specified percentage tables), and double declining balance (accelerated: 2/n × book value each year). Break-even analysis finds the volume where total revenue equals total cost. Replacement analysis uses the annual cost method to compare keeping an existing asset versus replacing it with a new challenger.

Supply Chain and Logistics

Inventory management: EOQ = √(2DS/H) where D = annual demand (units/year), S = ordering cost per order, H = holding cost per unit per year. Reorder point ROP = d × L where d = daily demand rate and L = lead time in days. Safety stock is added to the reorder point to buffer against demand and lead time variability. ABC analysis classifies inventory items by annual dollar value: A items (top ~20% of items = ~80% of value) receive tight control; C items (~50% of items = ~5% of value) receive minimal control. JIT (Just-in-Time) and lean principles aim to eliminate waste (muda): the eight wastes are Transportation, Inventory, Motion, Waiting, Overproduction, Over-processing, Defects, and Skills underutilization (TIMWOOD+S). Value stream mapping is used to identify and eliminate waste in a production process. Demand forecasting: simple moving average averages the last n periods; exponential smoothing uses F_{t+1} = α × A_t + (1−α) × F_t where α is the smoothing constant. Forecast accuracy: MAD (mean absolute deviation) and MAPE (mean absolute percentage error) measure average forecast error magnitude.

What exams does this BSIE practice test PDF prepare you for?

This practice test PDF is designed for two main examinations. First, the NCEES FE (Fundamentals of Engineering) Industrial exam — a computer-based, open-book exam required as the first step toward PE licensure in the United States. It covers industrial engineering topics including probability and statistics, engineering economics, work systems, manufacturing processes, quality, operations research, and supply chain management using the NCEES FE Reference Handbook. Second, the Philippine Engineering Licensure Exam for Industrial Engineers (BSIE Board Exam), administered by the Professional Regulation Commission (PRC), which covers engineering mathematics, industrial engineering theory, and professional practice topics relevant to the Philippine IE curriculum. Many practice questions are relevant to both exams due to significant content overlap in OR, quality, and work measurement.

What is the formula for EOQ and what does each variable represent?

EOQ stands for Economic Order Quantity — the optimal order size that minimizes total annual inventory costs (ordering costs plus holding costs). The formula is EOQ = √(2DS/H), where D is the annual demand in units per year, S is the ordering cost per order (also called setup cost), and H is the holding cost per unit per year (also expressed as I × C, where I is the carrying cost rate and C is the unit cost). The EOQ represents the point where annual ordering costs equal annual holding costs. When you order this quantity, total inventory costs are minimized. On the FE exam, you must also know the reorder point (ROP = d × L, where d is daily demand and L is lead time in days) and how to add safety stock when demand or lead time varies.

What is the difference between Cp and Cpk in process capability analysis?

Both Cp and Cpk measure how well a process fits within its specification limits, but they differ in whether they account for process centering. Cp = (USL − LSL) / 6σ compares the width of the specification spread to six times the process standard deviation — it tells you whether the process is capable if it were perfectly centered, but ignores where the process mean actually sits relative to the specification limits. Cpk = min[(USL − μ)/3σ, (μ − LSL)/3σ] adjusts for centering by taking the minimum of the distances from the mean to each specification limit, each divided by 3σ. A process can have a high Cp but a low Cpk if the mean is shifted close to one specification limit. A general rule of thumb: Cpk ≥ 1.33 indicates a capable process; Cpk < 1.00 means the process is producing nonconforming product. On most exams, you need to compute both and interpret what each reveals about the process.

How do you calculate the critical path using CPM?

The Critical Path Method (CPM) identifies the longest path through a project network — the sequence of activities that determines the minimum project duration. The procedure has two passes. In the forward pass, calculate Early Start (ES) and Early Finish (EF) for each activity: ES of the first activity = 0; EF = ES + duration; for activities with multiple predecessors, ES = maximum EF of all predecessors. In the backward pass, calculate Late Finish (LF) and Late Start (LS): LF of the last activity = EF of the last activity (or the target date); LS = LF − duration; for activities with multiple successors, LF = minimum LS of all successors. Total Float for each activity = LF − EF = LS − ES. Activities with zero total float are on the critical path — any delay to a critical activity delays the entire project. Free float = ES(successor) − EF, and represents how much an activity can be delayed without delaying the early start of any successor.
